摘要
应用等温热重法对６种生物质焦样与二氧化碳及水蒸汽的气化反应进行研究．由实验所得的质量－时间曲线确定反应的平均比气化速率，并利用速率方程ｄｘ／ｄｔ＝Ｋ（１－ｘ），求得６种焦样在与二氧化碳及水蒸汽气化反应中的表现活化能、指前因子等动力学参数．为生物质能源利用的研究提供了理论依据．
Chemical reaction kinetics of biomass gasification with carbon dioxide and steam at atmospheric pressure using six kinds of biomass--char was investigated in a thermobalance reactor. According to the experimental data, their mean specific gasification rates were determined. The rate equation dx/dt=K(1-x) is used to evaluste the apparent activation energy and preexponential factor for all the reactions.Results show that the rate equation proposed is reasonable.
