生物质气化技术的研究进展

Research Progress in Biomass Gasification Technology

生物质能是一种可再生能源,它来源于生物体(如植物、动物、微生物等)通过光合作用将太阳能转化为化学能,并以有机物的形式储存。生物质能可以在适当的条件下被转化为热能、电能、生物燃料等,是一种重要的替代传统化石能源的可持续能源。生物质气化作为生物质的开发路径之一,是利用生物质生产合成气的有效方式。本文综述了生物质气化技术的研究,包括传统气化技术、共气化技术、化学链气化技术以及超临界气化技术等。介绍了每个气化技术的实验研究,阐述了各个气化技术的特点;详细介绍了化学链气化中载氧体与共气化中掺杂剂的使用。本文旨在探索使生物质气化效率达到最优的方案,并列举了目前存在的局限性,为进一步发展生物质气化技术以及生物质气化研究提供有益参考。

As one of the alternative energy sources for fossil energy,biomass has attracted more and more attention.For one of the development paths of biomass,thermochemical conversion,especially biomass gasification,is an effective way to use biomass to produce syngas.This paper reviews the research of biomass gasification technology,including traditional gasification technology,co-gasification technology,chemical chain gasification technology and supercritical gasification technology.Experimental research on each gasification technology is introduced,and improvements and shortcomings of each new gasification technology compared to traditional gasification technology are expounded.The use of oxygen carriers in chemical chain gasification and dopants in co-gasification is introduced in detail.This article aims to explore the scheme of optimizing the biomass gasification efficiency,and lists the existing limitations,which provides a valuable reference for the further development of biomass gasification technology and biomass gasification research.
