摘要

Compared with the large amount of waste oil, recycled lubricants is still very few. It is necessary to develop new technology to dispose waste oil. Various technologies have been applied to regenerate waste oil, such as solvent extraction process, hydroprocessing and thin film evaporation. Among these technologies, hydroprocessing is one of the most attractive method, giving product oils of high quality. It can achieve the highest oil conversion and yield and has been successfully used in industry.
