Process for making a lube basestock with excellent low temperature properties |
摘要 |
A method for producing a lube basestock from a waxy feed is disclosed in which a feed containing to 50 wt % or more of wax is hydrotreated and stripped to lower the nitrogen and sulfur content of the feed. The feed is then hydroisomerized under conditions to 370° C. hydrocatalytically dewaxed with a catalyst comprising a mixture of a catalytically active metal on a zeolite dewaxing catalyst and an amorphous catalyst, or alternatively is solvent dewaxed and then hydrocatalytically dewaxed with the just described catalyst.
