摘　　要：利用热重分析仪研究了CO2气氛下的生物质半焦、煤焦及其混合焦的反应性,结果表明,在相同条件下,木屑半焦的气化反应性明显高于褐煤半焦.且参与反应的两种半焦,其反应性均随反应速率而提高,而温度也是影响其气化活性的重要因素.研究还发现,在温度高于1173K的条件下,混合物半焦的气化反应性较单一组分半焦的反应性差.The gasification of biomass coke, char and the mixture of biomass and coal in a thermogravimetric apparatus（TGA） was investigated. The results show that under the same conditions, the reactivity of sawdust char was significantly higher than that of lignite char. And the reactive of two char increased with the conversion rate, and the temperature also affect the gasification activity heavily. At the same time, the study also found that when the temperature is higher than 1 173 K, the mixture of semi-coke gasification reactivity is worse than that of single-component semi-coke.
