摘要: A process for producing a lubricating base oil having high oxidation stability, wherein the feed used to prepare contains at least 5 wt. % olefins, said comprising (a) determining weight percent of olefins present in by means 1 H NMR; (b) hydroprocessing under conditions selected reduce amount target value which has been pre-determined NMR produce desired stability; and (c) collecting stability from zone.
