摘要
本文给出了恒温条件下DAEM模型的最新理论阐述 ,得出了反应过程中活化能的解析表达式 ,并给出了得到反应过程中活化能变化曲线的具体步骤。对两种中国煤的气化行为进行的解析结果表明 ,该方法能够很好地反映气化过程中活化能的变化情况 ,解析结果能够与常规气化动力学的解析结果吻合。
The new theoretical elucidation of distributed activation energy model (DAEM) under isothermal conditions was given and the analytic expression of activation energy at the same levels of weight loss from different isothermal weigh loss curves was obtained and the procedures to obtain activation energy curves during whole reaction were proposed The application of the new theory to isothermal gasification of two Chinese coals showed that the changing activation energy during gasification can describe the process well and its average value agrees with the results from the classical kinetic analysis
