| Abstract | 基于简单碰撞理论，建立了生物质焦炭CO2气化反应速率的计算方法，找出了表征指数前因子大小的关键组合参数。在此基础上，对六种生物质及其脱灰焦炭的物理化学特性进行了检测分析，利用热重分析仪在800-1 000℃对各种生物质进行了CO2等温气化实验，将得到的指数前因子实验数据与模型分析结果进行对比。研究表明，指数前因子与构建的组合参数之间存在较好的相关性，建立的通用关系式可为气化反应规律的进一步阐明提供有益的参考。 |
| Other 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 800-1 000 ℃,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. |
