| 摘 要： | 本文回顾了生物质快速热解液化技术的国内外研究现状,重点叙述了初级生物油的化学组成和燃料性质,指出生物油是一种复杂的含氧有机混合物,具有水分含量高、氧含量高、热值低、酸含量高、安定性差和化石燃油不互溶等独特的性质;针对这些性质,介绍了几种常用的生物油精制提炼方法,包括催化裂解、催化加氢、高温热解气过滤、添加助剂、催化酯化、柴油乳化以及制备富氢合成气与费托合成,并分析了各种精制技术发展的关键问题。

| Abstract: | Recent progress in biomass fast pyrolysis technology for bio-oil production is briefly reviewed.The chemical composition and fuel properties of bio-oil are described.Bio-oil is a complex mixture of water and oxygenated compounds.It possesses many unique properties and characterized as high in water and oxygen content,low in caloric value,acidic and corrosive to common metal materials,chemically and thermally unstable,and non-miscible with petroleum fuels.Bio-oil has to be upgraded before it can be used as high-grade liquid fuels.Some upgrading methods relatively well developed are discussed,which include catalytic cracking,catalytic hydrotreatment,hot vapor filtration,solvent addition,catalytic esterification,emulsification with diesel,as well as production of hydrogen-rich syngas for Fisher-Tropsch synthesis.The key problems involved in these upgrading methods are also discussed. |
