摘要
使用美国TA公司的Q50热重分析仪对5种植物类木材生物质进行了热解的动力学研究,样品粒径为0．075～0．100mm．分别调查3种不同升温速率下热解温度对热解过程的影响,通过对热重分析(TG)、差分热重分析(DTG)曲线的分析,建立了相应的反应动力学模型,得到了不同木材的动力学方程中的表观活化能和频率因子,为热解过程的工业化设计提供了基础数据．
The kinetic results of pyrolysis process for five kinds of floristic wood biomass were studied using TGA Q50 thermogravimetric analyzer. The size of diameter of sample was between 0.075 mm and 0.100 mm. The effect of different heating rate on pyrolysis process was investigated respectively. A correspondingly kinetic model of pyrolysis process was established based on TG and DTG analysis and frequency factor and activation energies of different kinds of wood were attained,providing basic data to commercial design of pyrolysis process.
