Abstract

Mineral behaviors were investigated on the basis of the characteristics of three slag samples derived from pressurized ash agglomerate fluidized-bed gasification of Jincheng Anthracite (JC). Examination of the ash fusion temperature (AFT) shows that the AFTs of the slag samples in a reducing atmosphere (1:1 CO2/H2, volume ratio) increase in the order slag formed on the inner face (SI)
