摘要

在高压热天平上考察了神木煤显微组分在不同热解温度、压力和升温速率下的热解行为 .并利用分布活化能模型 (DAEM)研究了显微组分的热解动力学 .结果表明 :在相同的热解条件下

镜质组比丝质组有较高的挥发分收率 .随热解温度升高

镜质组和丝质组的挥发分收率增加 .热解升温速率和压力对镜质组和丝质组的挥发分收率略有影响 .DAEM的动力学处理表明 :镜质组的归一化热解速率高于丝质组

热解活化能较低.

Abstract

Pyrolysis of Shenmu coal maceral concentrates under different conditions was systematically investigated in TG-151 pressurized thermal balance.The pyrolysis kinetics was analysed by using Distribution Activation Energy Model (DAEM).The results indicated that vitrinite has higher yield of volatile matter than fusinite.With increasing temperature

the yield of volatile matter of vitrinite and fusinite increased.Pyrolysis pressure and heating rate showed little effect on the yield of volatile matter of macerals.The kinetic result illustrated that vitrinite has lower activation energy than fusinite.
