摘　　要：废油再生利用对资源再生、环境保护具有重要意义。本文对废油再生利用现状进行分析,指出了国内废油资源存在的问题。概述了不同再生技术包括硫酸-白土精制工艺、溶剂精制工艺、加氢精制、薄膜蒸发工艺、膜分离技术等,并在此基础上展望了我国废油再生工艺的研究趋势。The regeneration of waste oil is of great significance for resource conservation and environmental protection. This article analyzes the current situation of the regeneration of waste oil and points out the problems existing in domestic waste oil resources. The different regeneration technologies including sulfuric acid-clay refining process, solvent refining process, hydrofining, thin film evaporation process and membrane separation technology are summarized. On this basis, the research trends of China＇s waste oil regeneration process are prospected.
