Abstract: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 analysis. The 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 residues. The combustion behaviors of extraction residues show that the SD residue is more reactive and more easily burned than PS residue.
