Abstract: For the rational use of existing resources, increase the feed sources for lube oil hydrogenation and improve the quality of lube oil feedstock, hydrocracked tail oil is used as lube oil feedstock at the lube oil hydrogenation unit of Sinopec Shanghai Gaoqiao Branch in the following ways: hydrocracked tail oil blended with VGO, single hydrocracked tail oil and directly processing hydrocracked tail oil after vacuum distillation into iso-dewaxing unit. This paper focuses on the tracking analysis of these industrial applications. Results show that using hydrocracked tail oil as lube oil feedstock in either way, various high quality hydrogenated lube base oils can be produced.

Key words: hydrocracked tail oil , Lubricating oil , hydrogenation , base oil , industrial application
