摘　　要：随着石油化工产品市场价格的变化,各石化企业都在不断改进技术和工艺,为了更好地利用加氢裂化尾油,提高企业的经济效益,国内外厂家进行了大量研究,开发出许多用途。由于加氢尾油硫、氮含量甚低,芳烃含量低,饱和烃含量高,黏度指数高,是宝贵的高级基础油资源,以加氢裂化尾油为原料,完全突破了原油资源的限制,可以从劣质原油或者低黏度指数原料生产出高质量的润滑油基础油。With the change of market price of petrochemical products, petrochemical enterprises are constantly improving the technology and process. In order to make better use of hydrocracking tail oil and improve the economic benefits of enterprises, domestic and foreign manufacturers have carried out a lot of research and developed many uses. The hydrocracking tail oil is a valuable advanced base oil resource because of its low sulfur and nitrogen content, low aromatics content, high saturated hydrocarbon content and high viscosity index. Taking the hydrocracking tail oil as raw material, it completely breaks through the limitation of crude oil resources, and can produce high-quality lube base oil from inferior crude oils or raw materials with low viscosity index.
