地沟油制备生物柴油研究进展

Research Progress on Preparation of Biodiesel from Waste Oils

利用地沟油制备生物柴油,既可以实现地沟油的资源化利用,又可以大大降低生物柴油的生产成本。综述了以地沟油为原料,酯交换法制备生物柴油的原理及工艺,并对各种工艺进行了比较。

The preparation ofbiodiesel from waste oils could not only achieve reclamation of waste oils, but also greatly reduce the production cost ofbiodiesel. The principle and technics of producing biodicsel was reviewed through transesterification reaction using waste oils as raw materials. A variety of technics were compared.
