摘　　要：生物柴油的生产过程中都会产生副产物甘油,随着生物柴油的规模化发展,副产物甘油的合理利用成为生物柴油产业发展的关键问题之一.粗甘油的有效再利用有利于降低生物柴油的生产成本和解决环境污染问题.粗甘油可以通过各种工艺路线转化为1,3-丙二醇、环氧氯丙烷、乳酸、聚羟基脂肪酸酯、氢、二羟基丙酮和1,2-丙二醇等具有市场前景的高附加值产品.目前技术比较成熟并进入产业化阶段的粗甘油利用工艺路线是生物法生产1,3-丙二醇和化学法生产环氧氯丙烷,其他工艺路线多数还处在实验室研究阶段.本文以粗甘油综合利用为中心对目前研究进展和产业现状进行了综述.10% crude glycerol will be produced during the production of biodiesel. Therefore, in the industrialization progress of biodiesel, the effective utilization of crude glycerol becomes a major issue all over the world. The glycerol can be transformed into many products with highly added value, such as 1,3-propanediol, epichlorohydrin, lactic acid, polyhydroxyalkanoate, hydrogen, dihydroxyacetone and propylene glycerol, all of which show good market prospect. The processes of 1,3-propanediol fermentation and chemical epichlorohydrin production are being applied in a large scale, whereas other processes are still in the stage of laboratory research. Here we will present the technique and development status about the recycle of crude glycerol.
