生物质快速热解液化技术研究进展

摘要

总结了生物质热解液化技术在原料预处理、热解工艺和生物油精制3个方面的最新研究成果.在原料预处理方面,介绍了干燥、烘焙、压缩成型和酸洗4种方法;在热解工艺方面,列举了国内外具有代表性的热解反应器类型,重点介绍了催化热解和混合热解两种新工艺;在生物油精制方面,介绍了包括催化加氢、催化裂解、催化酯化和乳化等几种常用的生物油精制方法,并分析了各精制技术发展的关键问题.%The recent progresses in raw materials pretreatment,pyrolytic process and biooil upgrading for the fast pyrolysis of biomass to liquid fuel were reviewed.In the raw materials pretreatment,drying,torrefaction,compression moulding and acid-washing were introduced.In the pyrolytic process,typical fast pyrolysis reactors are enumerated and two novel pyrolytic processes,namely fast catalytic pyrolysis and co-liquefaction of both biomass and coal,were discussed.Finally,some upgrading methods were discussed,which included catalytic hydroprocessing,catalytic cracking,catalytic esterification,and emulsification with diesel.The key problems involved in these upgrading methods were also analyzed.
