The aim of this work is to provide a wide database of kinetic data for the most common biomass by thermogravimetric analysis (TGA) and differential thermogravimetry (DTG). Due to the characteristic parameters of DTG curves, a two-stage reaction model is proposed and the kinetic parameters obtained from model-based methods with energy activation values for first and second stages in the range 1.75·10(4)-1.55·10(5)J/mol and 1.62·10(4)-2.37·10(5)J/mol, respectively. However, it has been found that Flynn-Wall-Ozawa and Kissinger-Akahira-Sunose model-free methods are not suitable to determine the kinetic parameters of biomass combustion since the assumptions of these two methods were not accomplished in the full range of the combustion process.
这项工作的目的是提供一个广泛的生物质热重分析（TGA）和差热重分析（DTG）动力学数据数据库。由于 DTG 曲线的特征参数，提出了一个两阶段反应模型，并通过基于模型的方法获得了动力学参数，第一阶段和第二阶段的能量激活值分别在 1.75·10(4)-1.55·10(5)J/mol 和 1.62·10(4)-2.37·10(5)J/mol 范围内。然而，已经发现，Flynn-Wall-Ozawa 和 Kissinger-Akahira-Sunose 无模型方法不适用于确定生物质燃烧的动力学参数，因为这两种方法的假设在燃烧过程的整个范围内都没有得到满足。
