摘　　要：为了提升生物质气化气热值,减少焦油产率,越来越多的研究者开始试图从生物质组分的角度对热解气化特性进行探索.概述了碱金属、温度、压力、升温速率在热解气化过程中对生物质组分造成的影响,以及纤维素、半纤维素、木质素、萃取物和组分间相互作用对生物质热解气化过程造成的影响.提出了在二组分相互作用研究的基础上,应继续开展三组分相互作用的实验研究,以及生物质模化物和生物质原料化学结构差异对生物质原料热解气化特性的影响.此外,提出了采用单变量对照实验方法研究单变量的作用大小.In order to improve the heating value of the gaseous product and decrease the yield of tar from the pyrolysis and gasification of biomass,the pyrolysis and gasification characteristics of biomass components are investigated widely.The effects of the alkali, temperature,pressure,and heating rate on the pyrolysis and gasification are summarized. The effects of cellulose,hemicellulose,lignin and the interactions between them on the gasification and pyrolysis are also discussed.Besides those,the effects of the interactions among three components,the difference among the biomass model compounds,and the chemical structure of the biomass on the gasification characteristics require some further investigations on the foundation of the two components experiments.At last,the single variable controlled experiments are proposed to study the effect of the single factor.
