摘要:Pyrolysis behaviors of three weakly reductive coals from northwest China and one reductive Pingshuo (PS) coal were investigated in a thermogravimetric analyzer and a fixed-bed reactor. The results show that the pyrolysis behaviors of the weakly reductive coals are obviously different from that of the reductive coal despite their similar elemental composition. Compared with PS coal, the weakly reductive coals exhibit a lower weight loss and a lower rate of weight loss, and the peaks corresponding to the maximum rate of weight loss shift to high temperature. During pyrolysis in a fixed-bed reactor, the conversion and tar and gas yields of all the coals increase with temperature. The weakly reductive coals have lower conversions and tar yields than PS coal in the temperature range investigated, which is accordant with the weight loss in thermogravimetric analysis. The tars from coal pyrolysis were characterized by FT-IR, ultimate analysis, and (1)H NMR, and the combustion behavior of chars from different coals was compared on a thermogravimetric analyzer.
