摘　　要：随着能源需求的不断增长和环境问题的日益突出,生物质催化热解制备液体燃料技术成为一种可持续发展的能源利用方式。生物质直接热解生成的生物油成分复杂、热值低、含氧量高、酸性强,制约了生物油的应用。从热解机理、生物质预处理、催化剂和预处理和催化耦合技术等方面综述了影响生物油品质的主要因素。指出预处理技术普遍存在时间长的缺点,使用催化剂会导致生物油产率的降低,而预处理和催化耦合技术有望突破这2项技术难点;生物质快速热解定向制备富烃生物油、催化剂的选择与优化、预处理和催化耦合技术将是生物质快速热解制备高品质液体燃料的主要研究方向。With the increasingly growing demand on energy and prominent environmental crisis,catalytic pyrolysis of pretreated biomass has become a decent technical rout for the preparation of liquid fuels,a sustainable resource.However,the bio-oil generated from the direct pyrolysis of biomass has a complex composition,low calorific value,high oxygen content and strong acidity,which restricts its application.Thus,the main factors affecting the quality of bio-oil are analyzed from the pyrolysis mechanism,biomass pretreatment,catalyst selection and the coupling of pretreatment and catalytic pyrolysis.Pretreatment process will prolong the preparation time,and catalyst will lower the production of bio-oil.The coupling technology is a promising solution to the difficulties mentioned.To prepare high-quality liquid fuels by biomass pyrolysis rapidly,the following researches should target on how to make directional preparation on hydrocarbonrich bio-oil by biomass pyrolysis,select and optimize the catalysts,and couple the pretreatment process with catalytic pyrolysis.
