[more] ZnO based-double functional biochar (ZnO-BC) derived pine sawdust is prepared by microwave heating using simple one-pot method for levofloxacin (LEV) and Cr(¿) removal from wastewater. ZnO-BC has well developed pore structure with BET surface area of 915.47 m2/g, which also has well ZnO crystalline. These characteristics make ZnO-BC available as the adsorbent and photocatalyst for LEV and Cr(¿) removal wastewater. LEV and Cr(¿) adsorption date fit well with the Hill and Pseudo-second order equation with LEV and Cr(¿) adsorption amount of 193.42 and 21.03 mg/g, respectively. The LEV and Cr(¿) adsorption behavior are determined by the chemisorption process. The hydrogen bond, p-p interaction, surface complexation, pore filling are responsible for LEV removal. While the hydrogen bonding, complexation and redox are crucial to the removal of Cr(¿) from wastewater. LEV removal is 85.72¿97.19% at 15¿25 mg/L at 120 min, and Cr(¿) removal is 72.62¿99.9% at 40¿60 mg/L at 75 min under UV irradiation. The possible photocatalytic mechanisms of the LEV and Cr(¿) are further investigated and analyzed.

TG-FTIR-MS, infrared heating technique and response surface method (RSM) were employed to investigate the fast pyrolysis characteristics of WT in this study. Effects of temperatures and heating rates on products distribution and pyrolysis characteristics were researched in the reactor that was heated with rapid infrared heating. The TG-FTIR spectrum of volatiles indicates that there are S-O and N-H groups presented in volatiles. RSM was employed to optimize the experimental conditions to obtain a higher pyrolysis oil yield, indicating that the highest oil yield is 53 wt% at 625 °C and 25 °C/s. The pyrolysis product distribution of WT denotes that the infrared rapid heating significantly enhanced the yields of pyrolysis oil. Raising the temperature from 400 °C to 600 °C, the pyrolysis oil yield increased from 41.62 wt% to 50.66 wt%, while the temperature further rose to 700 °C, the oil yield dropped to 50.22 wt%. Meanwhile, as the heating rate elevated from 10 °C/s to 40 °C/s, the pyrolysis oil increased before decreasing and reached the maximum of 51.74 wt% at 30 °C/s. According to the GC¿MS results, the primary compounds in the pyrolysis oil are aromatic and aliphatic hydrocarbons with a content of over 70 %. Moreover, N/S-containing compounds in oil retain a low yield of 6 %. The SIMDIS results prove that the light fraction of oil increased by 13.43 % and 6 % as rising pyrolysis temperature and heating rate. The results of N2 adsorption and desorption show that the higher temperature promoted the development of the pore structure of char, while faster heating rates caused the collapse of the carbon pore structure.

[more] Two-dimensional graphene and metal carbide/nitride/carbonitride compounds (MXene) are widely recognized as promising electrode materials for electrochemical energy storage systems. Herein, MXene was hydrothermally self-assembled with graphene oxide to form three-dimensional porous aerogels, which were applied as electrode materials in symmetrical supercapacitors with both liquid and solid electrolytes. The fabricated supercapacitors exhibited excellent supercapacitive performances including superior capability, coulombic efficiency, and cycle stability. The specific capacitance of the aerogel-based supercapacitor assembled with liquid KOH electrolyte reached as high as 158.6 F g-1, while the fabricated all-solid-state supercapacitor displayed a power density of 1398.8 W kg-1 and an energy density of 33.3 Wh kg-1 at a current density of 1 A g-1. Notably, MXene was prepared via a more enviromentally friendly route by using molten Lewis acid instead of the traditional fluorine-involved agent as the etchant, thus efficiently limiting the hazardous chemicals to pollute the environment. This work provides a strong motivation for applying graphene and MXene composite materials in sustainable energy storage systems.

To enhance both efficiency... [more] Deep eutectic solvents (DESs) possess a remarkable capacity to absorb SO2, and their recyclability makes them highly promising for various applications. To enhance both efficiency and cost-effectiveness, this research combined porous activated carbon (AC) with a synthesized DES, ethylene glycol (EG) -imidazole (Im) - methyltriphenylphosphonium bromide (MTPB) (molar ratio 1:2:1). The effects of DES loading amount, space velocity, and flue gas flow rate on the SO2 absorption performance were investigated systematically. Results showed that the DES/ACs are SO2 high-performance adsorbents, particularly at high flue gas flow rates, achieving an optimal performance at a DES loading of 25%. Under conditions of 30 °C and a flow rate of 500 ml/min, the absorbent achieved an absorption rate of 0.066 g/g for low-concentration SO2 (1000 ppm). Four kinetic models: the Bangham, Ho pseudo-second-order, Lagergren first-order, and McKay second-order are applied to investigate the SO2 absorption dynamics. Both the Bangham and Ho models proved adept at predicting the SO2 absorption behavior on the surface of DES/AC, which suggests the underlying mechanism to be a combination of surface reactions and micropore diffusion. Thermodynamic analysis indicates that the primary driving force for SO2 absorption is the molar reaction enthalpy change. Hence, the DESs/AC absorbent shows great potential as a viable option for capturing SO2 in contaminated gas.

[more] The plastic layer permeability of five Australian coals was analyzed using two permeability measurement apparatuses operating under isothermal and thermal gradient induced coking conditions. In addition, the microstructure transitions across the plastic layers of the coals were analyzed using Synchrotron micro-CT. The permeability results and pore structure parameters derived from those analyses were correlated to better understand the mechanisms of plastic layer permeability. The high-rank coking coal with low fluidity showed a low plastic layer permeability over a wide temperature range and the generation of high internal gas pressure (IGP). Among all samples tested, the high-rank coal formed an intermediate plastic layer with the lowest number of isolated pores and the smallest size of open pores. This suggests that the lower deformability of the pore structures brought about by the low fluidity prevented additional pore growth and thus hindered pore interconnectivity. Additionally, it is possible that the low permeability in the resolidfied layer lends to pore expansion due to the difficulty of volatile release, evidenced by the larger volume of open pores within a larger size range of 50¿100 µm. It appears that the intermediate plastic layer with less interconnectivity solidified into the expanded open pore structures in the resolidified layer through the driver of high IGP, thus contributing to the low permeability. In addition, the formation of the low permeable barrier seemed to redirect the volatiles evolved from the plastic layer toward the loose coal side, which dramatically reduced the temperature range of the plastic layer during its progression from the wall to the center. These results suggest that the plastic layer permeability is influenced by several factors which affect mass transfer in the plastic layer. As such, various approaches were used in this study to observe phenomena of plastic layer permeability.

However, the sluggish oxygen reduction reaction (ORR) kinetics at the cathode still limits their overall performances. Herein, we fabricated a self-supported N-doped Co/Zn-carbon nanofiber membrane (Co/Zn@NCF) with superior activity and durability for the ORR. The liquid ZABs based on Co/Zn@NCF catalysts exhibited a cycling life of over 666 h with a charge/discharge voltage difference of 0.64 V and a voltage efficiency of 66 %. The fabricated flexible solid-state ZAB enables it to be stably charged and discharged under different bending angles. Strikingly the temperature-controlled scanning electrochemical microscopy (SECM) was developed to probe the local activity and selectivity of membrane-like Co/Zn@NCF at a submicrometer scale. This study provides an effective way for the development of self-supported catalysts for energy conversion devices and offers the in-operando technique for the analysis of catalysts in various operating temperatures.

[more] Catalytic hydrogen combustion (CHC) is a promising technology for clean, efficient, and safe energy generation in hydrogen-fueled systems such as fuel cells and passive autocatalytic recombination. This study investigates catalytic hydrogen combustion over the Pd-Cu/Al2O3 catalysts at low temperatures (<125 °C) to determine the rate law using a differential fixed-bed reactor. The particle size distribution and reducibility of the catalysts were studied to investigate the influence of the catalyst composition on its reactivity. Higher reduction temperatures promoted the formation of metallic Pd, leading to improved catalytic reactivity at the optimized composition of Pd0.75Cu0.25/Al2O3. Furthermore, the rate law of CHC over the optimized catalyst was determined by non-linear regression based on the experimental reaction rates obtained under different partial pressures of H2 and O2. The Langmuir-Hinshelwood single-site mechanism was found to provide the best description of the catalytic combustion of hydrogen at low temperatures.

[more] To reduce CO2 emissions in the FCC process, the post-combustion carbon capture and storage (CCS) technology has been first applied in the FCC process due to its ease of retrofit. However, the required chemicals and high energy consumption turn it into a high-cost method. Oxy-fuel combustion, with the use of different advanced air separation units (ASU), has the potential to be a cost-effective technology for carbon capture in the FCC system. This study first develops steady state models of a 1.4 Mt./a resid FCC unit operated in two carbon capture conditions, namely post-combustion and oxy-fuel combustion, by using Aspen Plus. Second, it compares the economic performances of three different ASUs in oxy-fuel combustion, which are cryogenic ASU, pressure swing adsorption (PSA) ASU, and vacuum pressure swing adsorption (VPSA) ASU. A comparative study on the performances of the industrial-scale CCS FCCUs is conducted for a comprehensive analysis. The analysis shows that the power consumption of the whole system reduces by 30¿50 MW when adopting the oxy-firing method, as compared to the post-combustion technology. The air-firing FCC unit with a VPSA air separation unit has the highest NPV and IRR (511.76 M$ and 23.45%) among these technologies. It presents the best performance in all aspects including CO2 recovery rate, energy consumption, and economics, which promises to become strongly competitive in CCS technologies of FCCUs.

I... [more] Using fast infrared heating technology to minimize the pyrolysis temperature differential and optimizing secondary reactions is advantageous for studying co-pyrolysis behaviors. In this study, the co-pyrolysis behaviors of waste tyres (WT) and corn stover (CS), including product distribution, pyrolysis kinetics, and thermodynamics, were studied using TGA-FTIR analysis and fast infrared heating reactor. The DTG curves for the co-pyrolysis of WT and CS significantly differed from the calculated values, implying that the pyrolysis intermediates produced by CS during the pyrolysis process may have synergetic effects with the pyrolysis of WT. The apparent activation energies using the Kissinger-Akahira-Sunose (KAS) and Flynn-Wall-Ozawa (FWO) methods were similar, 244.88 kJ/mol and 245.93 kJ/mol, respectively. The experiment results suggest that the bio-oil yield increased first and then decreased with a further temperature increase. The yield of bio-oil gradually increased from 35.36% to 46.06% as temperature rose from 500 °C to 700 °C; but the further increasing to 800 °C decreased the bio-oil yield to 40.72%. The aromatic compounds in tar gradually increased with increasing the temperature, while the aliphatic compounds increased initially and then reduced. Meanwhile, the oxygenated compounds first decreased and then increased with increasing the pyrolysis temperature. The yield of light oil components (C<10) increased from 5.11% at 400 °C to 7.71% at 700 °C. A further increase in the pyrolysis temperature to 800 °C reduced the light oil content to 4.93%.

In this study, characteristics and synergistic effects during the rapid co-pyrolysis of high alkali coal (HAC) and corn stover (CS) using infrared heating were systematically investigated. The co-pyrolysis liquid yield initially increased and then decreased with increasing the pyrolysis temperature. The synergistic effects clearly promoted the tar yield and quality. The co-pyrolysis tar yields increased with rising temperature, from 23.29 wt% at 500 °C to 28.87 wt% at 700 °C, before decreasing to 23.57 wt% at 800 °C. At 700 °C, the largest deviation was 63%. Moreover, the co-pyrolysis interaction had a maximal negative deviation of - 35% for CO2 mass at 700 °C, indicating that the co-pyrolysis of CS and HAC reduced carbon emissions. The tetracyclic and tricyclic aromatic hydrocarbons in PAHs were substantially reduced due to CS hydrogen radicals, and the quantities of the binary aromatic rings decreased by 50% with the increase in temperature. The presence of AAEMs in coal affected the bond breaking and reformation of molecular bonds within the tar components. Raman analysis and BET analyses suggested that AAEMs in HAC enhanced the reactivity of char. The interaction between the volatile of CS and HAC increased the amount of ammonia carbon and the number of active sites.

[more] Advancements in supercritical (SC), ultrasupercritical (USC), and advanced USC coal-fired power plants have been achieved through the development of enhanced materials utilized in advanced steam cycles and through the deployment of advanced emission control systems. These are referred to as high-efficiency low-emission (HELE) technologies, which may solve numerous issues associated with coal-based power generation. There is a clear global transition from subcritical to advanced power plant types and significant R&D work on HELE technologies. Therefore, this comprehensive review covers the latest HELE technology deployment in major coal-consuming countries and their R&D roadmaps to advance HELE technologies. In spite of the various advantages of HELE technologies, there have been numerous technical challenges relevant to achieving the HELE steam conditions and deploying low emission control technologies in the HELE systems. Hence, this review covers the technical challenges and the relevant recent research by using various coal combustion test facilities. The current focus for the progression from USC boilers to advanced USC boilers is a successful demonstration of the developed high-performance alloys under the advanced steam conditions. This review covers the current status of research and development of advanced USC (A-USC) materials and challenges based on the major material research programs.

[more] Among many supercapacitor electrode materials, carbon materials are widely used due to their large specific surface area, good electrical conductivity and high economic efficiency. However, carbon-based supercapacitors face the challenges of low energy density and limited operating environment. This work reports a facile self-assembled method to prepare three-dimensional carbon nanotubes/reduced graphene oxide (CNTs/rGO) aerogel material, which was applied as both positive and negative electrodes in a symmetric superacapacitor. The fabricated supercapacitor exhibited prominent capacitive performance not only at room temperature, but also at extreme temperatures (-20 ~ 80 °C). The specific capacitances of the symmetric supercapacitors based on CNTs/rGO at a weight ratio of 2:5 respectively reached 107.8 and 128.2 F g-1 at 25 °C and 80 °C with KOH as the electrolyte, and 80.0 and 144.6 F g-1 at -20 °C and 60 °C with deep eutectic solvent as the electrolyte. Notably, the capacitance retention and coulombic efficiency of the assembled supercapacitors remained almost unchanged after 20,000 cycles of charge/discharge test over a wide temperature range. The work uncovered a possibility for the development of high-performance supercapacitors flexibly operated at extreme temperatures.

Different innovative pyrolysis setups and the effect of reaction conditions such as pressure, temperature, catalyst type, biomass type, and reactor type on the formation of hydrogen and other value-added chemicals has been exploited. High temperatures and pressures together with application of catalysts was reported to favour the enhancement of hydrogen by promoting secondary pyrolysis reactions and hence the production of H2 gas. Compared to one-stage pyrolysis systems, pyrolysis data from two-stage pyrolysis reaction systems reported improved production of hydrogen and value-added chemicals due to the reforming of volatile matter in the second stage reactor. The polygeneration effect of biomass pyrolysis has also been reviewed, and it was observed that the polygeneration systems were significantly vital in covering the demand and supply of renewable energy.

In this work, different DESs were prepared with acetylcholine chloride as a hydrogen-bond acceptor. The effect of molar ratio of the hydrogen-bond acceptor and different hydrogen-bond donor, temperature, and different hydrogen-bond donors on NO absorption by acetylcholine chloride DESs was investigated systematically. The absorption experiment of NO by acetylcholine-methyl urea DES at an absorption capacity of 0.119 (g NO/g DES) when the molar ratio of acetylcholine chloride to methyl urea was 1 : 2 at 30¿40 °C. The absorption mechanism of NO by acetylcholine chloride DESs was determined by Fourier transform infrared spectroscopy and 1H nuclear magnetic resonance combined with quantum chemical calculation. The results indicated that NO with acetylcholine-methyl urea DESs by chemical absorption to form NONO structure, nitrogen-oxygen double bonds (N=O), nitrogen-oxygen single bonds (N-O), and nitrogen-nitrogen single bonds (N-N). The simulation results showed that nitric oxide formed two hydrogen bonds with N atoms on methyl urea: C-N···N and O=N···N=O. Thermodynamic properties showed that the ¿rHom for NO absorption in acetylcholine-chloride-type DES was -15.39 kJ/mol, which was more efficient for NO absorption/desorption.

[more] This study compares the performance, including reactivity and stability, of Pd¿Cu/Al2O3 and Cu/Al2O3 catalysts during catalytic hydrogen combustion in a temperature range of 20¿600 °C. The physicochemical and catalytic properties of catalysts were characterized using various analytical techniques. The reaction rates were measured using a fixed-bed reactor connected to a micro-gas chromatograph, and the rate law equations containing a term for steam partial pressure were determined. The effects of reaction temperature and catalyst composition on the reaction mechanism were investigated using in-situ Fourier-transform infrared spectroscopy analysis, and the generation of OH groups was analyzed to compare the reaction pathways of catalytic hydrogen combustion over Pd¿Cu/Al2O3 and Cu/Al2O3 catalysts. The results showed that at temperatures above 500 °C, Cu/Al2O3 achieved a comparable hydrogen conversion (96.5 and 98%) to that of Pd¿Cu/Al2O3. The rate-limiting steps of catalytic combustion over Pd¿Cu/Al2O3 and Cu/Al2O3 were the formation and breaking of metal-oxygen bonding, respectively. It was also found that the difference between the reactivity of Pd¿Cu/Al2O3 and Cu/Al2O3 was less pronounced under wet conditions.

Using recycled gas or exhaust gas as heat carrier in the pyrolyser is a promising way for improving its energy efficiency and reducing carbon emission. In this study, an experimental and numerical combined study is conducted to cost-effectively investigate the effect of utilising the recycled gas on coal pyrolysis in an industrial scale gas-heat-carrier pyrolyser. First, a lab-scale two-stage pyrolyser is employed to pyrolyze the low-rank coal samples to obtain the gas products composition. The experimental results are subsequently used in the CFD pyrolyser model as operating conditions to simulate the pyrolysis process of utilising the recycled gas as the heating carrier gas in an industrial scale pyrolyser. The comprehensive in-furnace phenomena evolution during the pyrolysis are illustrated, in terms of flow, temperature, gas composition, and pyrolysis characteristics. The effects of two carrier gases ¿ hydrocarbon-rich recycled gas and CO2-rich exhaust gas are examined and compared on the pyrolysis performance. The results indicate that compared to the exhaust gas, the employment of the pre-heated recycled gas as the heat carrier could significantly reduce the direct carbon emission (58%); improve pyrolysis efficiency (33%) and produce more valuable hydrocarbon gases (71.4%).

[more] New ternary deep eutectic solvents (DESs), including imidazole (Im), ethylene glycol (EG), and methyltriphenyl phosphonium bromide (MTPB), were synthesized at different molar ratios to absorb SO2in flue gas. Excitingly, the EG-Im-MTPB (1:2:1) DES has achieved the unexpected achievement of its absorption capacity being greatly improved to 0.65 g of SO2/g of DES (4.43 mol/mol) at 3000 ppm and 30 °C, which is the best performing DES for capturing SO2under the same conditions ever reported. The aftereffects of thermodynamic investigation demonstrate that there is a solid compound communication between EG-Im-MTPB (1:2:1) DES and SO2. In particular, the enthalpy change (¿rHm), entropy change (¿rSm), and Gibbs free energy change (¿rGm) were plainly determined as -50.45 kJ/mol, -114.57 J mol-1K-1, and -16.20 kJ/mol, separately. The Fourier transform infrared, 1H nuclear magnetic resonance, and quantum chemistry calculation results confirm that multiple active sites, including the N atom of Im and the Br atom of MTPB, are the main factors by which DES effectively absorbs SO2. Further, a UNIQUAC method by Aspen Plus V12 is set up for the SO2absorption process with 6000 m3/h flue gas, indicating that the EG-Im-MTPB (1:2:1) DES can completely absorb SO2in the flue gas when the consumption of DES is 26.8 m3/h.

This study identifies and summarises recent studies into the effect of biodiesel blends on engine performance and provides a classification of the literature. This study also aims to clarify the incentives for using biodiesel and the challenges still faced by researchers. Articles on biodiesel fuel and its blends in diesel and gas-turbine engines were collated and filtered based on the blending methods (complete substitution without diesel or partial substitution). Biodiesel utilization in gas turbines and its competitiveness with Jet fuel performance is one of the things that this study touched upon. Despite that, the gaps in using biodiesel instead of Jet-A still exist in turbine engines, so settling the challenges of using biodiesel in the aviation sector could be through using additives or substitutes. A total of 72 articles were selected and divided into two groups: single biodiesel blends and dual blend biodiesel. The fuel used and the engine types were identified for all articles, and the emission results and engine performance when biodiesel was used. This study contributes to the development and research into the primary system (such as compressor, combustion chamber, or turbine), challenges, and the limitations of the current studies.

The paper aims to brief the types of alternative fuels used for the past 30 years. Moreover, it includes the recent types of biofuels (especially biodiesel) and their blends with studies on the performances and the exhaust emissions for different engines. In this study, previous studies were analysed, the challenges faced by the researchers were examined, and incentives for using biodiesel fuel in engines were discussed. The engine performance and emissions when using biodiesels and their blends in different engine models were also surveyed. All biodiesels and their blends have demonstrated the ability to reduce emissions such as carbon oxide (CO), carbon dioxide (CO2), nitrogen oxide (NOx), particulate matter (PM) and hydrocarbon (HC) under various operating conditions, as well as the ability to improve the performance of the gas turbine. It is necessary to understand the combustion properties of fuels for their use in an engine. The contribution of this review is to help the engine manufacturers and researchers develop further research relating to readjusting and optimising the biodiesel engine and its relevant system.

Different weight ratios of KOH (VBC-urea mixture: KOH=1:0, 1:1, 1:2, and 1:3) have been used to optimize the porosity of NHPCs. Benefiting from the synergistic effect of the high porosity and N doping, the synthesized material with a high specific surface area of 687 m2/g and the N content at ~11 at% exhibited a high specific discharge capacity of 604.6 mAh/g at a current density of 0.1 A/g after 100 cycles and a high-rate performance of 245 mAh/g at 3 A/g. The developed material delivered a reversible capacity of 707.7 mAh/g at 0.05 A/g at the end of rate performance. The long-term cycling test performed at 1 A/g illustrates a stable and reversible capacity of 268 mAh/g after 1000 cycles with a coulombic efficiency of 100% and charge retention of 88%. The hierarchically porous carbon matrix with N doping can increase the Li+ diffusion efficiency and accelerate the charge transfer, thus leading to enhanced high-rate performance, superior reversibility, and high cyclic stability.

[more] Deep eutectic solvents (DESs) cannot absorb SO2 at high temperatures, due to the lower solubility of the toxic gas in DESs at high temperatures, limiting their wider uptake in industrial applications. To address this knowledge gap, we added Na2S to a series of DESs to improve SO2 adsorption capacity at elevated operating temperatures in this work. The experimental results show that the newly designed Na2S-EG-MTPB DESs can adsorb SO2 effectively up to 90 °C. Solid products resulted from the interaction of SO2 and Na2S-EG-MTPB DES is mainly elemental sulfur (S8) and sodium sulfite (Na2SO3). DESs can be reused for SO2 absorption for at least five times by adding additional Na2S. Therefore, Na2S-EG-MTPB DESs have great potential as substitutes for existing SO2 absorbents due to their excellent high temperature resistance, high SO2 absorption capacity and low cost.

These catalysts consisted of fly ash (as the carrier), Fe (ferric nitrate as the precursor) and Mn (manganese nitrate or potassium permanganate as the precursor). The NH3-SCR reactions were conducted in a specially designed fixed-bed reactor. The de-NOx and the resistance (SO2 and H2O) mechanism of catalysts were analyzed by X-ray photoelectron spectroscopy (XPS), NH3-temperature programmed desorption (NH3-TPD) and H2-temperature programmed reduction (H2-TPR). The results showed that the NOx conversion of Mn-Fe/FA was significantly higher than that of Mn-Fe/FA(N). The Mn-Fe/FA catalyst exhibited a wider operating temperature range (70~200¿). Moreover, Mn-Fe/FA catalyst maintained the initial NOx conversion (99%) for 4h in the H2O (5 or 10%) at 200¿. In the presence of SO2 and H2O at 200°C, Mn-Fe/FA was able to maintain over 75% NOx conversion after 4h. KMnO4, as a source of Mn in Mn-Fe/FA, promoted the redox properties of the corresponding catalyst and increased the concentrations of active metal ions (Mn4+, Fe3+) and chemically adsorbed oxygen. It was found that using KMnO4 as a source of Mn can inhibit the formation of metal sulfates.

It is of great significance to develop cost-effective mercury pollution control technologies of coal-fired flue gas. Among various mercury from flue gas removal methods, the application of existing air pollution control devices (APCDs) to remove mercury from flue gas is one of the most valuable methods because it doesn't need to install additional mercury removal equipment, reducing the cost of mercury removal. This review summarizes the recent progress of mercury from flue gas removal by APCDs (e.g., SCR denitration device, WFGD system and dust removal device). SCR denitration device can achieve partial removal of mercury in flue gas through combined with WFGD system, but easy inactivation and poor sulfur/water/heavy metals resistance of SCR catalyzers are still the main problems. WFGD systems can remove most of Hg2+ (80%-95%), but have low treatment ability for Hg0. Various oxidants can effectively oxidize Hg0 into Hg2+. However, traditional oxidants have high prices and secondary pollution due to the formation of by-products. Fabric filters (FFs), electrostatic precipitators (ESPs) and hybrid fabric filters (HFs) can all control the emission of mercury in the flue gas to a certain extent, especially can effectively remove most of HgP and part of Hg2+, but has low removal capacity for Hg0. Compared with ESP, FF has better capture efficiency for Hg2+ and Hg0, and a combination of ESP and FF, that is HF, can effectively improve the mercury removal capacity.

The sodium silicate solutions were treated by sol-gel method, and hydrophobic SiO2 aerogel was obtained via ambient pressure drying. The influence of sodium silicate modulus on the structure of aerogels was investigated through measurements of density, specific surface area and contact angle. The chemical reaction mechanism of nucleophilic substitution SN1 for hydrophobic modification of aerogel surface was proposed. The results show that the hydrophobic performance of aerogel is directly related to the number of ¿Si¿(CH3)3 attached to the surface. When sodium silicate modulus is equal to 2. 50, the best hydrophobic performance of aerogel is achieved. The density and specific surface area of aerogel increase with the increase of sodium silicate modulus. When the sodium silicate modulus is equal to 0. 75, the lowest density and specific surface area of aerogel are recorded, which are 0. 073 9 g/ cm3 and 588. 5 m2 / g, respectively.

Coal combustion is considered to be one of the major anthropogenic emission sources. Arsenic removal technology from coal combustion can be divided into three categories: pre-combustion removal, removal during combustion and post-combustion removal. The post-combustion removal is also called removal from flue gas, which includes several technological developments, namely, the removal using existing air pollutant control devices (APCDs), adsorption, traditional oxidation and advanced oxidation based on removal principle. This review summarizes the latest advances of these arsenic removal technologies. The performance, mechanism and characteristics of arsenic removal technologies were overviewed and analyzed. The merits and drawbacks, and the challenges and prospects of each arsenic removal technologies were discussed. It was found that pre-combustion removal, removal during combustion and removal using APCDs can achieve arsenic removal to a degree, but their removal efficiencies are usually low. Injection of adsorbent into the flue gases can achieve higher arsenic removal efficiency. Calcium-based adsorbents were found to be one of the most efficient ones for arsenic removal. Their shortcoming is the high-temperature sintering and deactivation caused by competitive adsorption of acidic gases. Other adsorbents suffer from low activity, small specific surface area, high cost, or/and little recovery. Further development of advanced adsorbents that are anti-sintering, anti-deactivation, large specific surface area, low-cost, separable, and recyclable should be the main focus in future research. Collaborative control of multiple systems such as removal during combustion, removal using APCDs or/and tail adsorption/oxidation is a promising strategy. Advanced oxidation technologies (AOTs) can achieve high arsenic removal efficiency (90¿100%), recovery of arsenic resources and potential simultaneous removal of multi-pollutants, possessing good prospect.

[more] To better understand the role of microwave and the mechanisms of thermal cracking and catalytic reforming of lignocellulosic bio-oils, this study compares the difference in the reaction characteristics between microwave-assisted and conventional heating of representative bio-oil model compounds. Syringol and guaiacol were selected as bio-oil model compounds. The effects of the heating method on the conversion of the model compound and the yield and composition of products were systematically investigated in the temperature range of 600¿700 °C. The results showed that high reaction temperature and microwave-assisted heating favoured the conversion of model compounds, and the conversions of syringol were generally higher than those of guaiacol under the same conditions (temperature, heating method). The heating method was found to greatly influence the yield and composition of products. The bio-oil obtained from conventional thermal cracking of model compounds contained phenolics, aromatic hydrocarbons, aryl alkyl ethers, and oxygen-containing heterocyclic compounds. In contrast, microwave-induced polarisation of poorly stable methoxy groups promotes the formation of phenolics, the concentration of the phenolic in the guaiacol and syringol bio-oil reached 62.5¿66.17 area% and 85.18¿87.65 area%, respectively, in the temperature range of 600¿700 °C. Catalytic reforming of model compounds showed that activated carbon catalyst drastically promoted the phenol formation, particularly under microwave-assisted heating, the phenol concentration reached 93.9¿97.97 area% in bio-oil during catalytic reforming of guaiacol. The formation of electron-hole pairs on the active metal sites induced by microwave radiation possibly enhanced the demethoxylation to selectively generate phenol due to the strong electron-donating ability of the methoxyl group. Microwave-assisted catalytic reforming of the model compounds was also beneficial for H2 formation because of the direct dehydrogenation of methyl radicals and the gas-phase reactions. The H2 concentrations of 81.07¿82.41 vol.% and 75.2¿79.16 vol.% were obtained during microwave-assisted catalytic reforming of guaiacol and syringol, respectively.

[more] This work introduces nanostructured carbon-based composite with enriched CNTs and microstructural defects from pomelo peel biomass precursors through successive chemical pretreatment, heteroatom N, S dual-doping and transition metal oxide loading (Ta2Oy) and its application for electrochemical oxygen reduction reaction (ORR) at room temperature. During the microwave pyrolysis process, volatile N, S-containing species from trithiocyanuric acid reactant were trapped and doped into carbonaceous biomass precursor to achieving the rich-defect porous nanotubes and abundant cavity structure. The effect of biomass pretreatment on the textural and structural properties of biochar and formed CNTs were systematically investigated. The impacts of single doping (N) using melamine and dual-doping (N, S) with trithiocyanuric acid on the structural and electrochemical characteristics of biochar were evaluated. An optimized PP-NS-600-Ta-900 electrocatalyst displayed remarkable ORR activity with a half-wave potential of 0.82 V (vs. RHE), a limiting current density of -5.75 mA cm-2 and an electron transfer number of 3.85. The results offer a useful archetypical template to design and construct reliable CNTs enriched biomass-derived biochar for possible electrochemical energy and storage application, illustrating its viability for utilization as ORR electrocatalyst in potential applications, like fuel cells and metal-air batteries.

In this study, pomelo peel (PP) was used to obtain N/S, Ta-doped carbonaceous-based composite electrocatalystviaa two-step microwave-assisted pyrolysis method. We found that the chemical pretreatment was crucial to isolate cellulose fibers and obtain the nanosheet-structure precursors from irregularly structured biomass and to yield structural defects induced by N, S co-doping. The latter serves as an active site to anchor TaOx, forming active ORR species. The obtained cell-PP-NS-700-Ta-900 composite exhibited most promising electrocatalytic activities (half-wave potential of 0.82 V (vs.RHE), a limiting current density of -5.24 mA cm-2, and an electron transfer number of 3.87) in 0.1 M KOH solution, which are comparable to that of the benchmark Pt/C electrode, while the former presented better selectivity and short-term durability. The synergy of the formed multi-heterointerface/chemical phases of Ta-based compounds and high content of N-pyridinic, N-quaternary, and N-nitride (metal-N) nitrogen functionalities in carbon were experimentally revealed as the major feature contributing to the enhanced ORR activity. This work sheds light on a sustainable and effective strategy to design and synthesize cost-effective and high-performance carbon-based composite electrocatalysts from fruit waste biomass and unlocks the superb intrinsic catalytic activity of transition metal compounds.

[more] High-efficiency, low-emissions (HELE) coal-fired power plant technologies operate with a higher thermal efficiency of the steam cycle for coal-fired power generation, reducing CO2 emissions per unit energy generation. They represent some of the primary and intermediate solutions to the world's energy security. Extensive numerical modeling efforts have been undertaken over the past several decades, which have increased our understanding of the technical problems in HELE boilers, including combustion and boiler performance optimization, ash deposition, and material problems at higher operating temperatures and pressures. Overall, the differences in the physical and chemical models, boiler performance, and ash deposition of oxy-fuel combustion in HELE boilers that recirculate CO2 and H2O in the boilers are also discussed in comparison with the combustion of coal in the air. This Review comprehensively summarizes the current research on numerical modeling to offer a better understanding of the technical aspects and provides future research requirements of HELE coal-fired boilers, including boiler performance optimization, ash deposition, and material problems. The effects of changes in the configuration and operating conditions are discussed, focusing on the optimization of boiler performance in aspects such as unburnt carbon and NOx emissions. The paper also reviews the retrofit and optimization of operating conditions and the burner geometry with the low-NOx coal combustion technologies necessary to operate the HELE power plants. In terms of ash deposition, the development of submodels, including particle sticking and impacting behaviors and their effects on the deposit growth predictions under different temperatures, are discussed. Numerical models of the material oxidation and creep in the austenitic and nickel-based alloys generally used in HELE conditions have been developed using the finite element method to predict the availability of advanced alloys and creep life in the actual service time of the boiler parts. The predictions of oxide scale growth and exfoliation on the steam-side and fire-side and the creep strength are analyzed. The review also identifies some further research requirements in numerical modeling to achieve the optimization of coal combustion processes and address the technical problems in advanced HELE power plant operations.

To extend the utilisation of coal resources, semi-coke has been introduced to blast furnace ironmaking process in recent years, however, there are still many issues unclear about the effect of semi-coke on ironmaking process. In this study, the possibilities of using semi-coke as alternative fuel for nut coke were studied. The characteristics of semi-coke including mechanical strength, high-temperature strength/reactivity, carbon gasification as well as direct reduction were studied and compared with small size metallurgical cokes (nut cokes). The results showed that semi-coke has higher CRI values, especially at higher temperatures and in a mix-charging pattern. Semi-coke was found to have a higher gasification reaction rate and depleted at lower temperatures. The reduction results showed that with participating of semi-coke the reaction starts at lower temperatures. In addition, the study suggested that semi-coke exhibits the advantages of low ash and sulphur contents, although it has lower mechanical strength, it would protect the lump coke by shifting the carbon gasification to itself, therefore, mixing semi-coke would benefit the blast furnace operation and lower the coke rate.

X-ray diffraction, Raman spectroscopy, transmission electron microscopy, and X-ray photoelectron spectroscopy were used to evaluate the properties of the FLG sample. A well-developed microstructure and higher graphitization degree were achieved under microwave heating at 1300¿ C using the S5% dual (Fe-Ni) catalyst for 20 min. In addition, the synthesized FLG sample encompassed the Raman spectrum 2D band at 2700 cm-1, which showed the existence of a few-layer graphene structure. The high-resolution TEM (transmission electron microscopy) image investigation of the S5% Fe-Ni sample confirmed that the fabricated FLG material consisted of two to seven graphitic layers, promoting the fast lithium-ion diffusion into the inner surface. The S5% Fe-Ni composite material delivered a high reversible capacity of 287.91 mAhg-1 at 0.1 C with a higher Coulombic efficiency of 99.9%. In contrast, the single catalyst of S10% Fe contained a reversible capacity of 260.13 mAhg-1 at 0.1 C with 97.96% Coulombic efficiency. Furthermore, the dual catalyst-loaded FLG sample demonstrated a high capacity¿up to 95% of the initial reversible capacity retention¿after 100 cycles. This study revealed the potential feasibility of producing FLG materials from bituminous coal used in a broad range as anode materials for lithium-ion batteries (LIBs).

The purpose of this study is predicting the engine performance and emissions rate for the KingTech K180 turbojet engine running on dual biodiesel and its blend with Jet-A fuel. Besides that, this paper explores the different effect between dual blends and single blend. The fuel parameters were calculated based on each fuel's physicochemical properties to produce nine different blends of dual biodiesel (B10-Jet, B30-Jet, B50-Jet, B70-Jet, and B90-Jet) and a single biodiesel blend (POME50: Jet-A50). Then the heat of combustion for each blend was obtained using the GasTurb Details-6. After that, the design point was determined of the specific engine and operates it using alternative fuels to analyze the performance and emissions characteristics (CO, CO2, and NOx). This study found that the B10-Jet blend gave the best specific fuel consumption (SFC) value, 42.43 (g/kN.s). It also produced a lower emissions rate for CO and CO2 than Jet-A fuel and other blends. While emission index NOx was high for all blends, except B10-Jet fuel value was close to Jet-A fuel emission value.

This paper employed the Solid-state 13Carbon Nuclear Magnetic Resonance (13C NMR), and the Synchrotron attenuated total reflection Fourier transform infrared (ATR-FTIR) microspectroscopy (Synchrotron IR) to study the transformation of the chemical structures in plastic layer samples. The light gases (mainly methane and hydrogen) released from coking process were analyzed using micro gas chromatography (micro-GC) connected to a small coking reactor heated in an electric furnace that simulated the formation of the plastic layers. The results show clearly that the total aromaticity increased consistently in the plastic layers for all coals tested, while the amounts of side-chains decreased significantly during the plastic layer. There was a clear trend showing that the total number of bridge bonds and the looped structures, indicating that the degree of cross-linking would increase through the plastic layer. The plastic layer samples from low fluidity exhibited cross-linking structures with a high degree of branching and aromaticity, while those from high fluidity coals formed cross-linking structures with a relatively low degree of aromaticity and branching but with a large number of bridge bonds and looped structures. The transferable methyl, methylene and hydrogen were strongly correlated to the cross-linking reaction and side-chain elimination in the thermoplastic region, which is reflected by the release profiles of methane and hydrogen gas during the plastic layer stage.

[more] The transformation of nitrogen in microalgae during entrained-flow pyrolysis of Chlorella vulgaris was systematically investigated at the temperatures of 600¿900 °C and pressures of 0.1¿4.0 MPa. It was found that pressure had a profound impact on the transformation of nitrogen during pyrolysis. The nitrogen retention in bio-char and its content in bio-oil reached a maximum value at 1.0 MPa. The highest conversion of nitrogen (50.25 wt%) into bio-oil was achieved at 1.0 MPa and 800 °C, which was about 7 wt% higher than that at atmospheric pressure. Higher pressures promoted the formation of pyrrolic-N (N-5) and quaternary-N (N-Q) compounds in bio-oil at the expense of nitrile-N and pyridinic-N (N-6) compounds. The X-Ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR) results on bio-chars clearly evidenced the transformation of N-5 structures into N-6 and N-Q structures at elevated pressures. The nitrogen transformation pathways during pyrolysis of microalgae were proposed and discussed.

The process is expected to improve the energy density of synthesis gas by capturing CO2 in a carbonator. Also, at the same time, the carbonator is expected to act as an ex situ tar removal unit, where tar cracking is expected to occur via catalytic reactions with CaO. The current work evaluates the feasibility of the proposed CL-BIGCC concept via thermodynamic analysis using Aspen Plus. Moreover, the tar cracking ability of CaO is demonstrated using thermogravimetric analyzer coupled to Fourier transform infrared spectrometer (TGA-FTIR) experiments. As part of the thermodynamic analysis, sensitivity analyses of the key process parameters, such as the calcium/biomass (Ca/B) ratio, steam/biomass (S/B) ratio, carbonator temperature, and calciner temperature, and their effects on net thermal-to-electricity efficiency have been studied in detail. The optimal values of key process parameters, such as a compression ratio of 5.1, an air/fuel mass ratio of 15, a Ca/B ratio of 0.53, a S/B ratio of 0.17, and carbonator and calciner temperatures of 650 and 800 °C, respectively, have been obtained. Furthermore, the CL-BIGCC process simulated in the current work was found to have a net thermal-to-electricity efficiency of ~25% based on the above optimal parameters, which is the highest among other conventional steam-based BIGCC processes. The biomass gasification (i.e., partial oxidation) experiments in a TGA-FTIR with a CaO/biomass ratio of 1:1 at different temperatures showed that CaO effectively catalyzed tar-cracking reactions.

The combustion characteristics of lignite coal, Chlorella vulgaris microalgae, and their blends under O2/N2 and O2/CO2 conditions were studied using a Thermogravimetric Analyzer-Mass Spectroscopy (TG-MS). During co-combustion of blends, three distinct peaks were observed and were attributed to C. vulgaris volatiles combustion, combustion of lignite, and combustion of microalgae char. Activation energy during combustion was calculated using iso-conventional method. Increasing the microalgae content in the blend resulted in an increase in activation energy for the blends combustion. The emissions of S- and N-species during blend fuel combustion were also investigated. The addition of microalgae to lignite during air combustion resulted in lower CO2, CO, and NO2 yields but enhanced NO, COS, and SO2 formation. During oxy-fuel co-combustion, the addition of microalgae to lignite enhanced the formation of gaseous species.

The effects of process parameters such as pyrolysis temperature and biomass/catalyst ratio on the yields and composition of pyrolysis products were investigated. Fast heating rates were achieved under microwave irradiation conditions. Gas chromatography-mass spectrometry (GC-MS) analysis of bio-oil showed that activated carbon significantly enhanced the selectivity of phenolic c3/30/2016 4:14:58 PMompounds in bio-oil. The highest phenolics content in the bio-oil (61.19 %(area)) was achieved at 300 °C. The selectivity of phenolics in bio-oil was higher for PT sample compared to that of PS. The formation of nanotubes in PT biomass particles was observed for the first time in biomass microwave pyrolysis.

A custom made hotplate was heated to 1000°C and the coal was allowed to heat naturally through conduction to produce a large thermal gradient typical of conditions in a coke oven. The sample was quenched, sectioned and analysed using laser desorption time of flight imaging mass spectrometry (LDI-TOF-IMS) to study the molecular changes that occur within the plastic layer and in the semi-coke. The raw coal was observed to have a molecular weight range between 500 and 20,000 Da with a peak occurring at 2000 Da. The plastic layer was observed to have a prevalence for increasing 500-1000 Da structures though this formed part of the larger molecular weight range. Resolidification of the plastic layer coincided with a rise in 4000 Da structures. The semi-coke spectrum had a series of repeating peaks separated by 24 Da extending from 1000 Da to 3000 Da. This was considered evidence of broad molecular ordering. A second phenomenon was observed in the semi-coke associated with low range molecular weights (50-300 Da). This appeared as high intensity signals in a molecular range typically considered as ion fragments (being too low in size to remain in the high vacuum environment). It was speculated that these low range structures may be associated with the coking of volatile tars exiting the hot-side of the plastic layer through high temperature semi-coke. Overall, this preliminary work provides a novel methodology to study the heating impacts during coking on a molecular level.

[more] The production of bio-oil rich in methoxyaromatics during catalytic pyrolysis of Eucalyptus pulverulenta (EP) was studied using a fixed-bed reactor in the temperature range of 300¿500 °C and the bio-oil composition was analyzed by using a GC¿MS. The results showed that the highest bio-oil yield of 38.45 wt% was obtained at 400 °C in the presence of Na2CO3, and the concentration of methoxyaromatics reached the maximum value of 63.4%(area) in the bio-oil. The major methoxyaromatics identified in bio-oil were guaiacol, syringol, 4-ethyl-2-methoxy phenol, and 1,2,4-trimethoxybenzene. The analysis of gaseous products indicated that CO2 was the major gas at low-temperatures and concentrations of H2 and CH4 increased with increasing pyrolysis temperature. Na2CO3 promoted the formation of methoxyaromatics, while NaOH seems to have enhanced the formation of phenolics. The mechanism of the formation of methoxyaromatics during pyrolysis of EP was proposed.

Gasification kinetics of demineralised, Ca-loaded, and Fe-loaded Morwell char were also studied. The grain model and random pore model were used to fit the gasification data. The random pore model fitted the experimental data better than the grain model. The activation energy was 189.05 kJ mol-1 for the CO2 gasification of Morwell coal char. With 2 % Ca loading, the activation energy increased to 204.53 kJ mol-1 due to lowering of the surface area. However, an order of magnitude increase in the pre-exponential factor indicated an increase in active reaction sites for the 2 % Ca-loaded sample, resulting in a net increase in gasification rate. 5 % Ca loading and 2 % Fe loading proved to be less effective in increasing the gasification rate. Analysis of the TG outlet gas also proved the effectiveness of 2 % Ca loading as a gasification catalyst.

A better understanding of the reducing characteristics of lignite char is necessary for the development of efficient DRI technologies. The application of lignite char as reductant in direct reduction of hematite has been investigated in this study, and the results are compared with those of lignite coal and graphite. Thermogravimetric analysis was used to analyze the thermal behavior of the composite pellets. Maximum iron oxide reduction rate occurred at 865, 829.5, and 920 °C when lignite coal, lignite char, and graphite were used as reductants, respectively, indicating that iron oxide can be reduced at lower temperatures in the presence of lignite char. X-ray diffraction analysis showed that complete reduction of hematite to elemental iron was achieved with lignite char after 15-min reduction at 1000 °C. Scanning electron microscopy-energy-dispersive X-ray analysis results showed that the atomic ratio of Fe/O was increased from 0.39 in pellets before reduction to 0.51, 0.55, and 0.71 after reduction by graphite, coal, and lignite char, indicating that lignite char reduced hematite to a higher degree compared to lignite coal and graphite.

In this study, the effects of drying methods (i.e., vacuum drying and N2 drying) on self-heating of Indonesian lignite during oxidation were investigated using a dual fixed-bed quartz reactor. The variation of coal temperatures was recorded and the release of CO2 and CO was measured by a gas chromatography. The pore volume and surface area of dried samples were measured using Brunauer-Emmett-Teller (BET) method. Mesopores in lignite initially increased and collapsed with further increasing drying intensity during drying in N2, resulting in a rapid self-heating rate of lignite within a critical moisture content range of 6-13%. However, vacuum drying caused a gradual increase in mesopores, which lead to a monotonic increase in self-heating rate with decreasing residue moisture content in lignite. The experimental results indicated that the production rates of both CO2 and CO during oxidation of raw lignite increased with reducing particle size and increasing gas flow rate, but decreased at lower moisture contents. Typically, the variation of production rates of both CO2 and CO as a function of particle size and gas flow rate followed a similar trend to that of raw lignite when the lignite was completely dried by the vacuum drying method. The impacts of lignite particle size and gas flow rate on the yields of CO2 and CO was limited due to less diffusion of O2 into small pores, suggesting that the oxidation reaction between lignite and oxygen has been shifted from diffusion controlled to kinetic controlled reactions.

The characteristics of NO reduction by copper and iron oxide catalysts supported on activated lignite chars (ALC) was studied using a fixed-bed reactor at 300 °C. The results showed that the impregnation of Cu on ALC resulted in higher catalytic reactivity during NO reduction compared with that of Fe. Chemisorption of O2 and NO on Cu/ALC catalyst was found to play an important role in denitrification. Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) analyses showed that chemically adsorbed oxygen facilitates the formation of C(O) complex and oxidation of Cu0 to Cu+ for Cu/ALC catalyst. The C(O) intermediates and C*production formed due to the fact that C/O2 reaction promoted the reduction of NO. It is suggested that the catalytic reaction of NO in this case comprised of C/O2 reaction, C(O)/NO reaction and formation of N2 and CO2. Cu seemed to have significantly promoted the C(O) formation and CO oxidation compared with Fe. The catalytic reactivity of Cu species for C(O) formation and CO oxidation followed the order of Cu0 > Cu+ > Cu2 +. Fe3O4 was believed to be the active phase in Fe catalyst. The oxygen and char-supported metal catalysts significantly promoted C/NO reaction, and therefore may lead to a lower operation temperature of NOx removal.

Catalytic microwave pyrolysis of PKS significantly enhanced the selectivity of phenol production. The highest concentration of phenol in bio-oil of 64.58 %(area) and total phenolics concentration of 71.24 %(area) were obtained at 500 °C using AC. Fourier transform infrared spectroscopy (FTIR) results indicated that concentration of OH, C. H, C. O and C. O functional groups in char samples decreased after pyrolysis. Scanning electron microscopy (SEM) analysis clearly indicated the development of liquid phase in biomass particles during microwave pyrolysis, and the mechanism is also discussed.

During desulfurization, the effects of process parameters on sulfidation properties were studied systematically. The physical and chemical properties of the sorbents were analyzed by X-ray diffraction (XRD), scanning electron microscope coupled with energy dispersive spectroscopy (SEM-EDS), Fourier transform infrared (FTIR) and BET surface area analysis. The results of desulfurization experiments showed that high pressure impregnation (HPI) enhanced the sulfidation properties of the sorbents at the breakthrough time for char-supported iron sorbents. HPI method also increased the surface area and pore volume of sorbents. Sulfur capacity of sorbents was enhanced with increasing sulfidation temperatures and reached its maximum value at 400 °C. It was observed that the presence of steam in coke oven gas can inhibit the desulfurization performance of sorbent. SO2 regeneration of sorbent resulted in formation of elemental sulfur. HPIF10 sorbent showed good stability during sulfide-regeneration cycles without changing its performance significantly.

Particles with a size range of 75¿105 µm with different moisture contents were injected in a bench-scale, electrically heated transparent reactor and the combustion of individual particles was observed with a high-resolution high-speed camera. Direct ignition observations indicated that most of the HL lignite particles underwent extensive fragmentation during ignition. Fragmentation was attributed to the explosive diffusion of volatiles and water vapor to the particle surface as a result of fast heating rate. Fragmentation reduced the particle size and increased the possibility of heterogeneous ignition of individual fragments. YN lignite particles on the other hand, underwent one-mode whole particle ignition upon heating. Higher moisture content caused a significant ignition delay in both lignite samples. 10% and 20% moisture in lignite samples resulted in around 83 and 160 ms delay in ignition for both coals. Higher intensity of fragmentation of HL particles during combustion compared to YN lignite resulted in shorter total particle combustion time at higher moisture contents. The findings of this study advanced the knowledge of the effects of moisture on ignition and combustion of low-rank coals.

[more] The effects of physical structure (pore structure) on behavior of water in lignite coal and activated carbon (AC) samples were investigated by using Differential Scanning Calorimetry (DSC) and low-temperature X-ray diffraction (XRD) techniques. AC samples with different pore structures were prepared at 800 °C in steam and the results were compared with that of parent lignite coal. The DSC results confirmed the presence of two types of freezable water that freeze at -8 °C (free water) and -42 °C (freezable bound water). A shift in peak position of free water (FW) towards lower temperature was observed in AC samples compared to the lignite coal with decreasing water loading. The amount of free water (FW) increased with increasing gasification conversion. The amounts of free and freezable bound water (FBW) in AC samples were calculated and correlated to pore volume and average pore size. The amount of FW in AC samples is well correlated to the pore volume and average pore size of the samples, while an opposite trend was observed for FBW. The low-temperature XRD analysis confirmed the existence of non-freezable water (NFW) in coal and AC with the boundary between the freezable and non-freezable water (NFW) determined.

[more] Well-aligned ZnO-ZnS heterojunction nanowire arrays have been synthesized via a novel wet chemical route in which ammonium persulfate was used as an oxidant to oxidize zinc foil directly followed by a sulfidization process to substitute oxygen with sulfur in the alkali solution. The structure and photocatalytic properties of ZnO-ZnS were analysed in comparison with those of ZnO nanowires. The formation mechanism of ZnO-ZnS heterojunction NW arrays arises from a combination of two different processes, namely a typical dissolution-crystallization process and a substitution reaction. Room temperature photoluminescence measurements indicate that ZnO-ZnS heterojunction NW arrays have an emission peak centered at 385 nm, and the PL intensity of the ZnO-ZnS heterojunction is lower than that of the ZnO NW arrays. The morphology and structure of the heterostructural products have been characterized by transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), and X-ray photoelectron spectroscopy (XPS). Due to the formation of heterostructures and a new transfer pathway of electrons from ZnS to ZnO, the composites show significantly improved photocatalytic activities than that of pure ZnO NW arrays. This study offers a novel way of fabricating semiconductor composites for high-efficiency photocatalysis applications.

[more] An Indonesian lignite was oxidized using a dual fixed-bed quartz reactor to examine the effect of moisture content, particle size and gas flow rate on low-temperature oxidation characteristics. The self-heating characteristics of dried samples have been further systematically investigated. During oxidation experiments, the temperature profiles of coal were recorded and CO2 and CO gases were analyzed using gas chromatography. The temperature of coal samples in air increased monotonically, successively exceeding the separation point temperature (SPT) and the crossing point temperature (CPT). SPT, the initial point of self-heating during oxidation, significantly depends upon water content of coal and its removal during drying. It was found from the SPT values that oxidation rate of lignite was highest at moisture content between 6% and 13%. The CO2 and CO production rates during the self-heating process increased with decreasing particle size, but these effects decreased gradually with increasing drying intensity due to "pore collapse" of lignite during drying. Both SPT and CPT for each dried samples decreased with decreasing particle size, indicating a more rapid self-heating at smaller particle size. The progressive decrease in dependence of the CO2 and CO production rates on gas flow rate with increasing drying intensity indicated that drying causes the transition of oxidation reactivity controlled by bulk diffusion to that by oxidation kinetics, which altered the net effect of heat loss and supply of oxygen in response to increasing gas flow rate, even resulting in change of the critical moisture range at high gas flow.

The desulfurization and regeneration experiments were carried out using a quartz fixed-bed reactor at ambient pressure. The effects of regeneration conditions, such as space velocity, temperature, and steam concentration, on the regeneration performance were examined. The crystal phase, chemical structure of activated components, and physical structure of sorbents before and after regeneration were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and Brunauer-Emmett-Teller (BET) surface area. The experimental results indicated that the char-supported Fe-Zn-Cu sorbents can be regenerated at temperatures above 500 °C. The optimal regeneration parameters with a space velocity of 5000 h-1, temperature of 700 °C, and steam concentration of 50 vol % have been obtained. The result of regeneration by steam suggested that the BET surface area of the sorbent after regeneration was larger than that of the fresh sorbent, and steam can restore the physical structure of the sorbent and expand its aperture during regeneration. Regeneration using SO2 was also studied under the optimal conditions. The XRD, FTIR spectroscopy, and XPS analyses indicated that the composite metal oxides in the sorbent formed during sulfidation were transformed into metal sulfides, which can be converted back to metal oxides during regeneration.

[more] ¿-Sialon based composites were produced using a vertical reactor by carbothermal reduction reaction under nitrogen using fly ash and lignite chars to examine the effects of mixing, carbon content, reaction temperature and sintering time. The influences of chars as a reductant were further investigated in comparison with graphite. The evolution of phase and morphology in samples were analyzed by X-ray diffraction (XRD) and scanning electron microscope (SEM). Mechanical stirring was favored to mix fly ash and chars, while ball-milling shove the chars with porous structure due to collisions of agate balls, preventing N2 penetration to the inner parts of reactants. When excess carbon was increased to 100%, a higher combustion reactivity of low-temperature chars resulted in the production of SiC phase. The evolution of ¿-Sialon with increasing reaction temperature showed the samples mixed with chars were more sensitive to reaction temperature than that with graphite. ¿-Sialon phase increased gradually with increasing sintering time to 6 h and decreased thereafter due to the decomposition or conversion of ¿-Sialon. These changes were more significantly for samples adding lignite chars. The optimal operation has been determined and rod-like ¿-Sialon whiskers with high aspect ratio appeared after performing the operation. In the growth process of whiskers, bead-shape whiskers were observed, suggesting that the growth mechanism was different from the conventional vaporliquidsolid (VLS) mechanism.

The sulfidation experiments were carried out using a fixed-bed quartz reactor under ambient pressure. The amounts of metals loaded into char were measured by inductively coupled plasma atomic emission spectrometry (ICP-AES). The crystalline phases and chemical structure of sorbents before and after sulfidation were characterized by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR), respectively. The morphology of sorbents was analyzed by using scanning electron microscope (SEM) with an energy dispersive X-ray (EDX) auxiliary. The experimental results showed that metal oxides as the active components were evenly dispersed on char as nanoparticles. The impregnation of active components was significantly improved by the ultrasonic-assisted impregnation method. When sorbents were prepared by ultrasonic-assisted impregnation, the metal oxide particles became smaller and more evenly dispersed on the char matrix which resulted in higher desulfurization efficiency and sulfur uptake capacity of the sorbents. The BET results showed that the physical properties of sorbents (surface area and pore volume) significantly improved when prepared by UAI method compared to MS method. The sulfidation temperature had a significant effect on desulfurization performance of char supported sorbents. The Fe:Zn molar ratio of 2:1, and impregnation time of 9 h were suggested as the optimal preparation conditions during ultrasonic-assisted impregnation.

Mesoporous activated carbons (ACs) were successfully prepared from lignite using KOH as activation agent at the temperature above 700°C. The pore structure and surface chemistry of the as-prepared ACs were characterized by means of nitrogen adsorption-desorption, X-ray diffraction, scanning electron microscope, transmission electron microscope and X-ray photoelectron spectroscopy. The results show that such prepared mesoporous ACs have a high specific surface area (~3036m<sup>2</sup>·g<sup>-1</sup>) with a hierarchical macro-meso-micro-pore structure and oxygen-enriched surface. The electrochemical performances of the ACs as electrode materials for electrochemical capacitors (ECs) were assessed by galvanostatic charge-discharge, cyclic voltammetry and cycling durability tests. It was demonstrated that the mesoporous ACs produced in this study possessed a maximum specific capacitance of 355F·g<sup>-1</sup> and 196F·g<sup>-1</sup> in 3M KOH aqueous and 1M (C<inf>2</inf>H<inf>5</inf>)<inf>4</inf>NBF<inf>4</inf>/PC organic electrolytes, respectively, at a current density of 50mA·g<sup>-1</sup>, and exhibited a desirable energy and power density with a superior cycling performance. The excellent capacitive behavior of the prepared mesoporous ACs in aqueous system is attributed to their unique macro-meso-micro-hierarchical pore structure with high surface area and oxygen-containing surface. Their superb electrochemical performance in the organic electrolyte is attributed to their well-developed mesoporous structure.

It can also offer a potential for conversion of coal into useful chemicals, allowing more efficient use of coal resources. In this study, a Chinese lignite was extracted by different solvents including CS2, ethanol, and acetone. The composition of the extracts was analyzed by GC-MS method. It was found that the CS2 extracts contained high amounts of aliphatic hydrocarbon. The ethanol and acetone extracts mainly contained oxygen-containing compounds. The effects of reaction temperature and residence time on coal oxidation and composition of extract residueswere also investigated. The results showed that lignite was readily oxidized in H2O2 aqueous solution at temperatures above 40 °C, and the oxidation behavior (oxidation rate, product distribution and yields) was strongly temperature dependent. Oxidation of extract residues in H2O2 solution was carried out at different temperatures. Water soluble products of oxidation were analyzed using the GC-MS. Aliphatic hydrocarbons were present in all oxidation steps. The relative content of esters in all oxidation stepswas also high. The chemical structure changes of coal, the extract residues, and the oxidation residueswere studied using FTIR technique. The results indicated that the extract residues had lower intensity of aliphatic hydrogen compared to raw coal. The aromatic carbon concentration remained relatively unchanged when oxidized at temperatures below 30 °C, then decreased slightly with increasing the oxidation temperature.

The effects of pyrolysis temperature and biomass type on the yield and composition of pyrolysis products were investigated. The average activation energy for pyrolysis of biomass samples by FWO and KAS methods in this study were in the range of 211.09-291.19kJ/mol. CO2 was the main gas component in the early stage of pyrolysis, whereas H2 and CH4 concentrations increased with increasing pyrolysis temperature. Bio-oil from Chlorella vulgaris showed higher content of nitrogen containing compounds compared to lignocellulosic biomass. The concentration of aromatic organic compounds such as phenol and its derivatives were increased with increasing pyrolysis temperature up to 700°C. FTIR analysis results showed that with increasing pyrolysis temperature, the concentration of OH, CH, CO, OCH3, and CO functional groups in char decreased sharply.

[more] Sulfidation properties of char-supported Fe-Zn-Mo sorbents prepared by ultrasonic impregnation method were investigated during simultaneous removal of H<inf>2</inf>S and COS from coke oven gas (COG) using a fixed-bed quartz reactor. Sorbent samples before and after sulfidation were analyzed using X-Ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). The experimental results showed that the addition of Mo significantly improved the desulfurization properties (i.e., breakthrough time, sulfur capacity and desulfurization efficiency) of Fe-Zn sorbents. Desulfurization reactions were exothermic and thermodynamically favorable in the temperature range of 200¿400 °C. Thermodynamic analysis of the sorbents indicated that higher concentration of H<inf>2</inf>S and lower concentration of H<inf>2</inf> favors the reaction of metal oxides with H<inf>2</inf>S to form metal sulfides.

The pyrolysis temperature was recorded continuously by inserting a thermocouple into the samples. Temperatures as high as 1170 and 1015°C were achieved for peanut shell and Chlorella vulgaris. The activation energy for MW pyrolysis was calculated by Coats-Redfern method and the values were 221.96 and 214.27kJ/mol for peanut shell and C. vulgaris, respectively. Bio-oil yields reached to 27.7wt.% and 11.0wt.% during pyrolysis of C. vulgaris and peanut shell, respectively. The bio-oil samples from pyrolysis were analyzed by a gas chromatography-mass spectrometry (GC-MS). Bio-oil from lignocellulosic biomass pyrolysis contained more phenolic compounds while that from microalgae pyrolysis contained more nitrogen-containing species. Fourier transform infrared spectroscopy (FTIR) analysis results showed that concentration of OH, CH, CO, OCH3, and CO functional groups in char samples decreased significantly after pyrolysis.

In this study, char-supported sorbents were prepared by loading iron, cerium, and molybdenum into a Chinese lignite through co-precipitation, and the sorbents were used for dry desulfurization of coke oven gases. Desulfurization efficiency of the sorbents was examined using a fixed-bed reactor in a temperature range of 473-673 K using a simulated coke oven gas. A gas chromatograph equipped with both a flame photometric detector (FPD) and a thermal conductivity detector (TCD) was used to analyze gas composition, while X-ray diffraction and scanning electron microscopy were used to examine chemical phases and the dispersion pattern of the active constitutes of the sorbents. The experimental results showed that the highest desulfurization efficiency and sulfur capacity appeared at 673 K. The reactivity of the nanosized active components in the char increased with increasing the desulfurization temperature in the temperature range of 473-673 K. In the case of Fe-Mo-impregnated sorbents, Fe and Mo combined together to form complex Fe-Mo oxide phases. The introduction of Mo in the sorbent is found to greatly increase the sulfur capacity and desulfurization efficiency of the Fe sorbent supported on activated chars. The addition of Ce leads to noticeable improvement of the performance of Fe sorbent during sulfidation. The mechanisms and factors influencing the sulfidation reactions have also been discussed. © 2014 American Chemical Society.

The authors use the mixture of iron oxide with other metal oxides (e.g. Ce) supported by ash from a coalgangue- fired power plant to prepare high temperature desulphurization sorbents. The two-step desulphurization process is comprised of a first-stage desulphurization of removing majority of sulfur followed by a second-stage desulphurization to remove the remaining sulfur species. The process is integrated with effective sulfur recovery through direct elemental sulfur production during the regeneration of Fe/Ce based sorbents. Preliminary studies on sulfidation using a quartz fixed-bed reactor demonstrated that the Fe/Ce-based sorbents prepared in this study was able to remove >97% sulfur in the temperature range of 400-600°C. Simultaneous removal of organic and inorganic sulfur species was achieved.

[more] Conversion of fuel-N into HCN and NH3 during the pyrolysis and gasification of coal and biomass in steam were compared using fluidized-bed/fixed-bed and two-stage fluidized-bed/tubular reactors. During the pyrolysis and gasification of coal and biomass in steam, the thermal cracking of volatile-N was the main route for the formation of HCN while a small amount of HCN was formed from the breakdown of relatively unstable N-containing structures in char. Our results indicate that once the fuel-N in both biomass and coal is condensed/ polymerized into the solid-phase char-N during the gasification in steam, the main nitrogen-containing gaseous product from char-N would be NH3. However, the thermal-cracking/reforming of volatile-N constitutes an additional important route of NH3 formation during the gasification of biomass (e.g., cane trash) in steam while this route is negligible for the gasification of coal. The selectivity of char-N toward HCN and NH3 is largely controlled by char-N stability and/or the availability of H and/or other radicals during the gasification of coal and biomass. © 2007 American Chemical Society.

Water-gas-shift reaction experiments were carried out on a fixed-bed quartz reactor in the temperature range of 300-450 °C. The results indicated that iron highly dispersed in the char matrix with a particle size smaller than 50 nm demonstrated a high catalytic activity. Carbon material in the char was able to effectively prevent the agglomeration of nano-iron particles and maintained a high catalytic activity of the catalyst during water-gas-shift reaction. The effects of gasification conditions on the catalytic activity of the char catalyst were also investigated. © 2007 American Chemical Society.

Iron was loaded into the acid-washed Loy Yang brown coal using ferric chloride aqueous solution. Gasification experiments were carried out using a quartz reactor at a fast particle heating rate. The yield of char was determined by directly weighing the reactor before and after each experiment. Gases were analysed using a GC with dual columns. The overall gasification rate of a char increases greatly in the presence of iron. The transformation of iron species during pyrolysis and gasification was examined using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results show that both reduced-iron (a-Fe and ¿-Fe) and magnetite (Fe3O4) highly dispersed in a char can catalyse the gasification of the char with steam. In particular, the char from iron-loaded coal samples gives much higher yields of H2 than a char from the acid-washed coal under similar conditions. The mechanism for the enhancement of hydrogen production in the presence of iron is discussed. © 2005 Elsevier Ltd. All rights reserved.

This study aims to investigate the effects of ash or ash-forming species on the conversion of fuel-N during gasification. A Victorian (Loy Yang) brown coal and a sugar cane trash were gasified in two novel fluidised-bed/fixed-bed reactors where the interactions of ash with char and/or volatiles could be selectively investigated. Our results show that the interaction of ash with char and/or volatiles could lead to increases in the yield of NH3 and decreases in the yield of HCN although the increases were not always matched exactly by the decreases. Loading NaCl or Na2CO3 into the brown coal was also found to affect the formation of HCN and NH3 during gasification. In addition to the possible catalytic hydrolysis of HCN into NH3 particularly at high temperatures, two other causes were identified for the changes in the HCN and NH3 yields. It is believed that some ash species could migrate into the char matrix to affect the local availability of H radicals or to catalyse the formation of NH3 selectively. The interactions of ash (or Na loaded into the coal) with volatiles could enhance the formation of soot-N, which would be gasified favourably to form NH3. © 2006 Elsevier Ltd. All rights reserved.

According to the mechanisms of desulfurization, it is feasible to prepare sorbents for desulfurization with semi-coke and metal oxides due to the similarity of semi-coke and activated carbon in their properties.

The reactions via soot formation on a solid surface (e.g., sand) provide important routes for the conversion of quinoline-N into HCN and NH3 during pyrolysis and steam reforming at temperatures below 850 °C. The main route for the HCN formation is the breakdown of the N-containing intermediates as the intermediates undergo cracking and polymerization reactions to form soot. The subsequent hydrogenation of soot-N is an important source for NH3 formation when the temperature is 850 °C or lower. The gasification of soot in steam can also account for a small portion of the observed HCN. Above 850 °C, the hydrolysis of HCN into NH3 alters the final yields of HCN and NH3 during the reforming of quinoline with steam. During the reforming of quinoline with steam at 800 °C, the addition of coal ash, simulating the conditions in a coal/biomass gasifier, remarkably enhances the hydrolysis of HCN into NH3, although the activity of the ash diminished rapidly with time due to possible changes in the physicochemical forms of active species in ash. © 2006 American Chemical Society.

The catalyst samples were examined using X-ray diffraction and TEM. Iron is highly dispersed in the char matrix as magnetite with a particle size smaller than 50 nm. The catalyst is found experimentally to be very active for the water-gas-shift reaction at temperatures as low as 300°C. A conceptual process is proposed for the integrated catalytic production of hydrogen based on the gasification of solid fuels such as coal and biomass. Within the proposed process, the char-supported nano Fe catalyst in a moving-bed reactor has the potential to carry out integrated functions of chemical heat pumping, hot gas cleaning, pollutant (particularly NH3 and H2S) abatement and water-gas-shift reaction catalysis. © 2006 Institution of Chemical Engineers.

[more] Biomass-nitrogen conversion during the pyrolysis and gasification of a cane trash in steam was investigated using a fluidised-bed/fixed-bed reactor and a fluidised-bed/tubular reactor. Our results indicate that the thermal cracking of volatile-N is the main route of HCN formation although the thermal cracking of char-N also contributes to the formation of HCN. There are three major routes of NH3 formation: 'hydrolysis' of N-containing structures in the solid phase during the primary pyrolysis, thermal cracking and gasification of solid nascent char as well as the thermal cracking and reforming of volatile-N. Under the current experimental conditions, the hydrolysis of HCN does not appear to be an important route of NH3/HNCO formation. © 2004 Elsevier Ltd. AH rights reserved.

[more] Effects of pressure on the formation of HCN and NH3 during the pyrolysis and gasification of Loy Yang brown coal in steam were investigated using a pressurised drop-tube/fixed-bed reactor. The NH3 yield increased with increasing pressure during both pyrolysis and gasification. Increasing pressure selectively favours the formation of NH3 at the expenses of other N-containing species. The changes in the yield of NH 3 with increasing pressure were mainly observed in the feeding periods both during pyrolysis and gasification and were closely related to the formation and subsequent cracking of soot both as a result of intensified thermal cracking of volatile precursors inside the particles and as a result of volatile-char interactions after the release of volatiles. While the corresponding HCN yield during pyrolysis showed little sensitivity to changes in pressure, the HCN yield during gasification in steam showed some increases with increasing pressure. Our data indicate that the direct hydrogenation of char-N by H radicals, favoured by the presence of steam, is the main route of NH 3 formation during pyrolysis and gasification. The direct conversion, either through hydrogenation or hydrolysis, of HCN into NH3 on char surface during the pyrolysis and gasification of brown coal is not an important route of NH3 formation. © 2005 Elsevier Ltd.

[more] Char structures evolved during the devolatilization process have been found to play a significant role in the subsequent processes (e.g., char combustion and gasification) and to influence the ash formation mechanisms. In the present paper, a mathematical model has been developed based on the multibubble mechanism to simulate the char structure evolution process. The model is the first to provide predictions of heterogenous char structures evolved during devolatilization (e.g. cenospheric char, foam structure, or dense char structure) as well as transient particle swelling ratios, based on the ultimate and proximate data of the given coal. The devolatilization process is divided into the preplastic stage, plastic stage, and resolidified stage. Bubble number conservation, mass, and force balance are formulated during the plastic stage to predict the transient swelling ratio and resultant char structures. Experiments have been conducted using a single coal particle reactor (SPR) and a drop tube furnace (DTF) with density-separated coal samples prepared using the sink-float method. The SPR experiments confirm that bubble behavior is responsible for the swelling of the particles that develop plasticity on heating. The analysis of the DTF chars shows that the swelling ratio and porosity decrease with increasing the coal density. Chars from lowdensity samples are mainly Group I chars (porosity >80%), while high-density samples yield mainly Group III chars (porosity <50%), and the medium-density samples contain a mixture. The predicted swelling ratio, porosity, and char type distribution of the chars of the density-separated samples are consistent with the experimental data.

The product gas compositions from the coal pyrolysis were analyzed by a gas chromatography (GC). Experimental results show that Zn had noticeable catalytic effects on lignite pyrolysis. With the increase in Zn content, lignite weight loss increases during pyrolysis. However, there was an optimum content for amount Zn into the coal. Pyrolysis temperature had a great impact on the composition of pyrolysis gas. As the pyrolysis temperature increased, char yield decreased and gas yield increased. There existed a temperature that tar yield reached its maximum value. © (2014) Trans Tech Publications, Switzerland.

IWO is a relatively novel numerical stochastic optimization algorithm. By incorporating the reproduction and spatial dispersal of IWO into the traditional PSO, exploration and exploitation of the PSO can be enhanced and well balanced to achieve better performance. In a set of 15 test function problem, the parameters of IW-PSO were analyzed and selected, and the computational results show that IW-PSO can effectively obtain higher quality solutions so as to avoid being trapped in local optimum, comparing with PSO and IWO. © (2013) Trans Tech Publications, Switzerland.

The mining of coal creates large amount of gangue which not only occupies a large area of land but also generate environmental problems. On the other hand, coal gangue is a low calorific fuel which should be utilized properly. A few small power plants are current running or under construction in China. However, due to its high ash content, coal gangue generates a large amount of ash when it is combusted in power plants. The ash from power stations not only contributes to emissions of fine particulates in the air but also results in the contamination of soil. The utilization of coal gangue ash is therefore important to reduce China s environmental pollution. In this paper, current status of the research and development of gangue ash utilization in China is reviewed. The gangue ash has found its application in a wide range of areas, such as road construction, chemicals, agriculture fertilizers, etc. Some ash samples were collected by the authors from a coal gangue fired power plant in Fuxin, northeast China. Characteristics of the ash were analyzed by using XRD, SEM, Laser sizer and other techniques. Because of its physical structure (e.g., large surface area and porosity) and its composition (i.e., containing mainly SiO2, Al2O3 and CaO) the gangue ash has a potential in the application of iron-based sorbents for high temperature removal of hydrogen sulfide from coal gas. A desulphurization sorbent was prepared by using the mixture of iron oxide and the gangue ash collected from the power plant. The structure and property of the surbent were examined using XRD, SEM and other techniques.
