A LUBE BASESTOCK WITH EXCELLENT LOW TEMPERATURE PROPERTIES AND A METHOD FOR MAKING

摘要

A method for producing a lube basestock from a waxy feed is disclosed in whi ch 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 .degree.C, hydrocatalytically dewaxed with a catalyst comprising a mixture o f 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.
