XRD in coal research

Only coals of a certain rank soften, swell, and eventually resolidify upon heating to produce coke, an essential material for the production of steel in the blast furnace route. Such thermoplastic development is attributable to the fusibility of coal organic constituents and their interaction with the coal inorganic components during pyrolysis. My research aims to provide additional insight into these complex phenomena by conducting research on maceral concentrates separated from parent coals of different ranks. X- ray diffraction (XRD) analysis on the separated maceral is conducted at the EMX-Ray Unit, The University of Newcastle, to determine the overall percentage of their crystalline mineral matter and the relative proportions of each mineral. This information coupled with petrographic analysis helps to identify the association between coal organic (maceral) and inorganic (mineral matter) components and assists with the prediction of the resultant coke strength.
