从元素含量、化学成分、稳定性、粘度、热值等方面详细叙述了热解生物油的性质，介绍了生物油的精制和利用技术，其中对近年来出现的生物油热蒸气直接催化精制、利用表面活性剂改良生物油使其直接用于柴油机等新技术给予了特别关注，对催化剂在生物油精制和利用过程中的影响也作了重点叙述。

Element content, chemical composition, stability, viscosity and heat value of bio-oil are analyzed based on many literatures in this paper. Some new technologies to refine and to utilize bio-oil are introduced such as directly catalyzing bio-oil vapor, and adding surfactants into bio-oil,so that it can be used directly in diesel engine. The catalysts and their effects on the refining and utilization of bio-oil are discussed.
