摘要: 生物质气化是一种在高温氧化性介质作用下将生物质热分解为可燃性气体的热解技术。为了提高生物质气化过程中气化效率、调整可燃性气体组分的含量和去除焦油,通常需要采用不同气化介质、改变气化条件或添加不同的催化剂。本文重点综述了生物质气化所使用的介质和催化剂种类以及气化条件对气化气组分,主要是H2和CO的影响规律。最后对未来生物质气化研究进行了展望,提出了几个待研究解决的问题。

Abstract: Biomass gasification is a kind of pyrolysis technology in which biomass materials was converted into combustible gas by means of thermal decomposition of raw materials in high temperature oxidbillity media. In the process of gasification, the variables such as gasification medium, gasification conditions and catalysts were commonly employed to improve gasification efficiency and adjust combustible gas components and eliminate tar that was produced from the thermal decomposition of biomass materials. The effect of types of gasification media and catalyst, and gasification conditions on the components of gaseous products, i.e., H2 and CO, were reviewed emphatically in this paper. Finally, the future development of biomass gasification was prospected and some problems were presented.
