摘　　要：对鄂尔多斯原煤和酸洗改性煤进行热分析,原煤熟裂解主要经过三阶段,且在450～480℃阶段达到失重速率峰值.随着升温速率的提高,失重量也随之增加,且在快速热裂解阶段,失重速率也随之增加,经酸洗改性理后的煤样失重量大于改性前的煤样.Thermal analysis of the raw coal and acid modified coal in ordos,raw coal pyrolysis is mainly through three stages,and to achieve weight loss rate in 450~480℃ phase peak.With the increase of heating rate,lose weight also will increase,and the fast pyrolysis stage,the weight loss rate also will increase,after pickling modification principle of coal sample weight loss is greater than before modification of coal samples.
