In order to know how the mineral matters in coal change during the coal conversion reaction, XRD and CCSEM analyses were carried out with Beulah Zap raw coal and 800℃ char. It was confirmed that calcite (CaCO_3) was mainly converted to lime (CaO) during gasification, while pyrite (FeS_2) was converted to pyrrhotite (FeS) and hematite (Fe_2O_3). Kaolinite (Al_2Si_2O_5(OH)_4) did not changed to metakaolinite, but to complicated alumino-silicates.
