摘　　要：用热重分析法对炼焦配煤常用单种煤的热解动力学特性及热失重过程进行了研究,分析了各单种煤的热解缩聚特征,研究了各煤种热解活化能与频率因子的变化情况,发现煤样热解分三个阶段,活化能与频率因子有相同的变化趋势,并且与煤种有关。Single coking coals have been studied using TGA in terms of thermal weight loss in order to investigate the characteristics of the pyrolysis kinetics of single coking coals. The characteristics of pyrolysis condensation of single coking coals are analyzed, and the changes of activation energy and frequency factor are studied. According to the pyrolysis kinetics analysis and thermal weight loss, there are 3 stages in pyrolysis, the changes of activation energy and frequency factor have the same trend, and both of them are related to coal types.

关 键 词：热解缩聚 动力学 活化能
