摘　　要：利用热重分析仪对石煤与2种生物质的混合物进行混合共热解的实验研究。结果发现高碱金属含量的存在使得玉米秸秆对石煤热解的促进效果好于锯末;升温速率为20℃/min时,混合物中石煤热解所需的活化能最低,其中玉米秸秆-石煤混合热解所需活化能低于锯末-石煤;生物质与石煤的混合比例为3:7时,石煤的热解速率最快。The pyrolysis experiment of stone coal mixed with two kinds of biomass is studied by using thermogravimetric analyzer. The results showed that high content of alkali metal makes corn stover better than sawdust in promoting effect of stone coal; The activation energy of the stone coal in the mixture is the lowest when the heating rate is 20 ℃/min. And the activation energy of stone coal-corn stalk mixture is lower than that of stone coal-sawdust mixture;Stone coal has the maximum pyrolysis rate when the mixing ratio is 3：7.
