Abstract: The clean gasoline and diesel produced from biocrude hydro-upgrading will be an important development direction of biofuel technology in the future. The composition，characteristics of biocrude，and the current research and development of the biocrude technology are introduced. The development of fast pyrolysis，catalytic pyrolysis to produce biocrude and hydro-upgrading technology are discussed. The technology of biocrude oil production and its upgrading to cleaner transportation fuel is still in the phase of research and development，and there is still a big gap from now to the commercialization of the technology. The biocrude would occupy an important position in petroleum alternatives. China should speed up the pace of research and development，so as to realize commercialization and satisfy the increasing demand of transportation fuel.

Key words: biocrude, fast pyrolysis, catalytic pyrolysis, clean fuel

摘要： 通过生物原油加氢改质生产清洁汽柴油是未来生物燃料技术的重要发展方向。本文介绍了生物原油的组成、特性及生物原油技术的研发现状，重点对快速热裂解、催化裂解生产生物原油及其加氢改质技术进展进行了探讨分析。结论指出，国内外生物原油及其改质精制生产清洁运输燃料技术目前仍处于研究开发阶段，离工业化生产还有很大的差距，预计未来生物原油在石油替代进程中必将占有重要地位，我国要加快生物原油技术研发步伐，争取早日实现工业化生产，以满足市场日益增长的交通燃料需求。
