生物质热解过程中焦油脱除方法的研究进展

Research Progress of tar Removal Methods During Biomass Pyrolysis

我国生物质资源丰富,生物质热解制氢技术作为实现“双碳”目标的有效途径已经得到了广泛应用,但过程中产生的焦油严重阻碍了其工业发展,因此明晰焦油的转化机制对生物质气化技术的发展有重要意义。本论文介绍了焦油的主要成分和形成机理,并对国内外主要的焦油脱除方法做了系统综述,为进一步研究提供参考。

China has abundant biomass resources,and biomass pyrolysis hydrogen production technology has been widely used as an effective way to achieve the"dual carbon"goal.However,the tar produced during the process seriously hinders its industrial development.Therefore,clarifying the conversion mechanism of tar is of great significance for the development of biomass gasification technology.This paper introduces the main components and formation mechanism of tar,and provides a systematic review of the main tar removal methods at home and abroad,providing reference for further research.
