摘　　要：采用热重分析法(TGA)对白桦、豆杆和褐煤单独及混合热解特性进行了研究。通过对不同混合比例热解与单独热解对比发现:生物质的热解过程主要分为三个阶段,褐煤的热解过程主要分为四个阶段。混合热解中,热解峰值温度Tmax高于理论值;热解最大速率Wmax、热解失重率α小于理论值;最大析出温度Tp随着生物质混合比例的增加而减少;主热解阶段的活化能E与指前因子A存在动力学补偿效应。种种变化说明生物质与褐煤产生了一定的协同作用。Two biomass and one lignite were co-pyrolyzed. Using the thermogravimetric analysis（TGA）method to investigate the pyrolysis performance of each material, as well as their mixtures. Comparing different mixing co-pyrolysis with individual pyrolysis showed that there were three stages in biomass pyrolysis process and four stages in lignite pyrolysis process. In the co-pyrolysis process, Tmaxwas higher than the theoretical value,Wmaxand α were less than the theoretical value, Tpof co-pyrolysis decreased with increasing amount of biomass in blends, and the dynamic compen-sation effect happened between E and A in the main pyrolysis stage. The variations indicated that biomass and lignite made the synergistic effects.
