建立动力学方程是正确了解生物质热解过程的关键,研究生物质快速热解机理必须获得生物质在快速热解条件下的动力学方程。为此,介绍了国内外学者对生物质快速热解动力学的研究,对提出的动力学模型进行了总结并分类介绍。生物质在快速热解条件下的动力学模型可以分为单步整体模型、竞争反应模型、半总体模型、焦油二次裂解模型和综合模型等。
Building the kinetic models is a key step for exploring the mechanism of fast pyrolysis of biomass.So it is necessary to get kinetic parameters before studying the process of biomass fast pyrolysis.Kinetic models obtained by researchers in recent 10 years were classified and introduced.The models could be classified: one step global model,competing model,semi-global model,secondary tar cracking model,synthesis model,and so on.
