摘　　要：应用热重—差示扫描(TG-DSC)同步热分析仪对小麦秸秆、棉秆、花生壳和白松等生物质进行了热解实验研究。通过对实验所得小麦秸秆的DTG和DSC曲线对比分析,对生物质热解过程进行了详细的探讨。在DSC曲线上扣除水分的影响后,对其积分得出热解过程需热量的规律。实验数据为生物质热解工艺的能量平衡分析和经济性分析提供了参考。这种方法可以推广到其他生物质以及垃圾等热解和燃烧过程的研究中。Simultaneous thermal analyzer was used to analyze pyrolysis of biomass. Wheat straw, cotton stalk, peanut shell and pine powder sample was put into Platinum crucible with lid on a high accuracy DSC-cp sample holder in the furnace. The process was investigated in detail through the comparison of DTG (differential thermal gravimetry) and DSC (differential scanning calorimetry) curves of wheat straw. After the water influence in the DSC curves was eliminated, the relationship of caloric requirement for biomass pyrolysis with the temperature of the four kinds of dry biomass was obtained by integrating the DSC curves.The experimental data are useful for the heat balance analysis and potential analysis of the process. The method also can be used in investigating the caloric effects in combustion, pyrolysis of biomass and municiple solid waste.
