Abstract: Through upgrading, bio-oil by biomass fast pyrolysis is promising technology for diesel or gasoline substitute. Biomass to bio-oil is considered extensively a controllable technology with a fast progress. But the upgrading or refinery of bio-oil is complex. The paper summarized recent development of the technology of bio-oil upgrading or refinery, and the research way of aqueous of bio-oil for hydrogen and the unaqueous for oil is a promising scheme，and some suggestion for using bio-oil by classification is put forward.

摘要： 生物质快速热解制取的生物原油，经过精制提质，具有柴油或汽油的特点，可用于车用燃料。生物原油制取技术发展较快，技术较可控，但其精制提质过程复杂，需要突破的技术障碍明显。本文对国内外的生物原油精制提质研究进展与技术发展进行了系统的综述，认为生物油水相制氢和油相制油的技术路线更具发展前景，并提出了生物原油分级利用的建议。
