INFLUENCES OF MINERAL MATTER ON HIGH TEMPERATURE CHAR GASIFICATION
IntroductionEfficient gasification of a particular coal depends sensitively on the high-temperature behavior of the ash produced by that coal. The traditional parameters used to classify coals for gasification applications are the ash softening and fusion temperatures. DT, ST and FT, together with various empirical formulae based on ash chemistry, have been widely used to determine the influences of mineral matters on high temperature coal gasification. Although the ash-fusion test and ash chemistry provide useful guidelines, they are often unreliable in predicting the behavior of coals in real gasification processes, hi this study, the high-temperature (1100-1500℃) transformations and reactions undergone by the mineral-derived phases in Huainan coal ash samples under reducing conditions were investigated by X-ray diffraction and the CO2 gasification of chars prepared at different conditions were also taken according to GB/T 220-2001 to investigate influences of mineral matter on high temperature char gasification.
