摘      要：Two kinds of residues,obtained from extraction of one weakly reductive coal,Shenfu-Dongsheng coal(SD),and one reductive coal,Pingshuo coal(PS),with sub-and supercritical water on a semi-continuous apparatus,were characterized by calorific value analysis and XPS analysis,and the combustion behaviors of residues were investigated by thermogravimetric *** results show that the residues have higher calorific value than raw coal samples,and SD residue has higher calorific value than PS residue.C-C,C-O and pyridinic nitrogen,pyrrolic nitrogen are the dominant form of C,O and N on the surface of raw coal samples and their extraction *** combustion behaviors of extraction residues show that the SD residue is more reactive and more easily burned than PS residue.
