CO2气氛下生物质焦气化反应动力学模型研究:Ⅱ.指数前因子
Modeling study on the biomass char gasification kinetics under CO2 atmosphere: II.Pre-exponential factor
摘要
Abstract
Based on the simple collision theory (SCT),the calculation method of biomass char gasification rate was developed and the combined parameters to characterize the pre-exponential factor were found.Furthermore,some experimental tests for six acid-washed biomass chars,such as the isothermal gasification and so on,were performed under CO2 atmosphere,using a thermo-gravimetric analyzer (TGA) over the temperature ranges of 800-1000℃,respectively.Through the comparison of experimental data and modeling results,it is found that a good agreement is made and the developed model equations can provide an effective guidance to clarify the general gasification law of biomass chars.关键词
