In the present paper, a new distributed activation energy model has been developed, considering the reaction order and the dependence of frequency factor on temperature. The proposed DAEM cannot be solved directly in a closed from, thus a method was used to obtain the numerical solution of the new DAEM equation. Two numerical examples to illustrate the proposed method were presented. The traditional DAEM and new DAEM have been used to simulate the pyrolytic process of some types of biomass. The new DAEM fitted the experimental data much better than the traditional DAEM as the dependence of the frequency factor on temperature was taken into account.
在本文中，考虑到反应级数以及频率因子对温度的依赖性，开发了一种新的分布式活化能模型。所提出的分布式活化能模型（DAEM）无法直接以封闭形式求解，因此采用了一种方法来获得新DAEM方程的数值解。给出了两个数值例子来说明所提出的方法。传统的DAEM和新的DAEM已被用于模拟某些类型生物质的热解过程。由于考虑了频率因子对温度的依赖性，新的DAEM比传统的DAEM能更好地拟合实验数据。
