摘要

采用自行研制的大物料热重分析装置研究生物质(秸秆)在800、900、1 000℃等温条件下的热解特性。结果表明

大物料热重反应时间短

各个阶段反应相互叠加

热重分析曲线(DTG)出现多个峰值。采用化学动力学法拟合了秸秆在等温热解过程中的质量损失率与时间的单方程宏观模型

求取了活化能E和指前因子A

得到等温热解反应动力学方程

计算得到质量损失率和反应时间的理论曲线与试验曲线相吻合。

Abstract

By adopting the self-developed bulk material thermo-gravimetric analysis device

the pyrolysis behavior of biomass(stalks) under uniform temperature condition of 800 ℃

900 ℃

and 1000 ℃ has been studied.Results show that the reaction time of bulk material pyrolysis is short

the reaction in each stage is mutually piled up

and many peak values appeared on the curve of thermo-gravimetric analysis.By using the method of chemical dynamics

the single equation macroscopic model between mass loss and time in uniform temperature pyrolysis process has been fitted

obtaining the activation Energy E and the forward-indicating factor A

as well as the dynamics' equation of pyrolysis reaction under uniform temperature.The theoretical curve between mass-loss and time obtained from calculation tallies well with the curve obtained from test.
