润滑油基础油加氢联合工艺研究

Study on the Hydrogenation Combined Process of the Lube Base Oil

介绍了采用临氢降凝—加氢精制串联方法制取润滑油基础油的实验结果。用此种方法所得到的基础油收率在 45 %以上 ,粘度指数 10 0 ,含硫、氮、芳烃等杂质较少 ,降凝效果较好 ,有良好的工业应用前景。

This paper introduce the test result preparing lube base oil by hydroprocessing technology. Through this method, the base oil yield is over 45 %, and viscosity index is 100. It contains low sulfur, low nitrogen and low aromatics. It has better effect of reducing pour point and better commercial application prospects
