摘　　要：采用热重分析方法,以氮气为载气,在室温和973K之间,以三种升温速率(10,20,30K/min)对三种生物质废弃物试样(稻秆、稻壳和白松木屑)进行热解实验。确定了起始分解温度D。采用了生物质整体热解分区、生物质化学组分热解分区、活化热解与消极热解分区等三种热解分区方法进行分析。由于三种试样化学成分的差别导致热解特性的差异。得到了三种试样热解动力学参数。The thermal degradation of three biomass waste varieties （rice stalk, rice husk and wood sawdust （baisong）） were investigated at three heating rates （10, 20, 30 K/min） in nitrogen atmosphere using the technique ofthermogravimetric analysis between ambient temperature and 973 K. The initial degradation temperature, TD, was determined. Three thermal degradation subzones analysis methods, the whole pyrolysis zones, the main compounds pyrolysis zones, and the active and passive pyrolysis zones, were applied. The chemical diversity caused the difference of thermal degradation characteristics of the three biomass waste samples. The kinetic parameters ofthermal degradation of the three biomass wastes were given.
