摘要： 利用TG-DTG技术研究了橡胶催化热解过程，并采用多升温速率和单升温速率相结合的方法对热解第一阶段动力学数据进行分析。推导出橡胶热解反应级数为3/2，反应动力学方程为 ，表观活化能为148～162 kJ/mol，指前因子lnA为28～32。

Abstract: The catalytic thermal decomposition of rubber was studied with TG-DTG. The thermal kinetic data were analyzed according to the single and multiple scan methods. The decomposition process of rubber was a 3/2 order reaction, whose kinetic equation was as follows： , and whose activation energy and pre-exponential factor were 148—162 kJ/mol and 28—32 respectively.
