生物质气化是生物质利用研究的一个重点。生物质气化包含生物质的热解和热解所得焦炭的气化两个过程。不同的热解条件将得到具有不同气化活性的生物质焦炭，不同热解条件制取的焦炭的动力学参数也不相同。本文主要概述了热解条件对生物质焦气化活性的影响。同时基于阿伦尼乌斯公式介绍了生物质焦等温气化动力学参数的两种获取方法，非等转化率法是通过选择动力学模型中的结构因子f(x)来获取动力学参数，而等转化率法是通过避开选择动力学模型中的结构因子 f(x)来获取动力学参数。基于简单碰撞理论提出了获取等温气化动力学参数的新方法，对阿伦尼乌斯公式中的指数项、指前因子 A 提出了明确的物理意义。基于简单碰撞理论的等温求解气化动力学参数方法类似于基于阿伦尼乌斯公式的等温求解气化动力学参数方法。

Biomass gasification is a key point in the research of biomass utilization. Biomass gasification process includes biomass pyrolysis and char gasification. Different char with different reactivity will be made by different pyrolysis process for the biomass. The kinetic parameters of different chars produced by different pyrolysis conditions are not the same. This paper summarized the effects of pyrolysis conditions on gasification activity of biomass char. At the same time based on Arrhenius formula, two methods acquiring kinetic parameters of isothermal gasification for biomass char were described. The first method is to obtain the kinetic parameters by selecting the structure factorf(x) of kinetic model, and the second method is to obtain the kinetic parameters by avoiding the selection the structure factorf(x) of kinetic model. Finally, based on Simple Collision Theory new methods obtaining kinetic parameters of isothermal gasification for biomass char was put forward to present the obvious physical meaning of the index terms, and the pre-exponential factorA of Arrhenius formula. Methods acquiring kinetic parameters of isothermal gasification based on Simple Collision Theory are similar to these acquiring kinetic parameters of isothermal gasification based on Arrhenius formula.
