Abstract

Transformation of mineral matter is important for coal utilization at high temperatures. This is especially true for blended coal. XRD and FTIR were employed together to study the transformation of mineral matter at high temperature in blended coals. It was found that the concentration of catalytic minerals, namely iron oxides, increases with an increasing ratio of Shenfu coal, which could improve coal gasification. The transformation characteristics of the minerals in blended coals are not exactly predictable from the blend ratio. This was proved by comparing the iron oxide content to the blending ratio. The results from FTIR are comparable with those from XRD. FTIR is an effective method for examining variation in mineral matter.
