A process for making a lube base stock from a lower molecular weight feedstock

摘要

A process for making a lube base stock wherein a highly paraffinic feedstock (with boiling points within the range of from 258° to 1100° F.) is dehydrogenated to produce an olefinic feedstock, which is oligomerized to produce an oligomerized product, which is separated into a lighter fraction and a heavier fraction. That heavier fraction has a flash point within the lube base oil range.
