地沟油的回收与重利用综述

文章将地沟油对人体的危害,鉴别地沟油的各种方法,制备肥皂,制备工业油脂、工业油酸、硬脂酸,制备生物柴油、生物基烯烃、生物塑料、油溶性有机稀土化合物、橡胶隔离剂等方面的应用进行了综合分析,其中着重介绍了采用固相微萃取气相色谱——质谱联用鉴别地沟油和地沟油制造生物柴油发展前景与应用成果。总的认为地沟油的综合利用生产成本低,可以就地取材,就地使用,能够较好解决地沟油的出路问题,并能够带来可观的经济效益。

This paper summarizes that the harm of drainage oil to oil.. It also analyses the application of drainage oil ,which can be human health and the varied ways to identify the drainage made into commercial grease, industrial oleic acid , stearic acid, biodiesel, bio-based olefins, bioplastics, oil-soluble organic rare earth compounds. Among this paper, it lay emphasis on one of the methods to identify drainage oil which apply SMEG-GC and the development prospect and the application results of biodiesel preparation with drainage oil. We think the comprehensive ultilization of drainage oil is cost-effective. Furthermore, the spot utilization exactly solve the problem with recycle of the drainage oil and also make substantial economic benifit.
