Abstract
Foots oil, the by-product left when high quality wax is recovered by a solvent dewaxing process, is usually used as cracker feed stock. There is disclosed a method of converting it to higher quality lubricant base stock by subjecting such to catalytic hydroprocessing utilizing a ZSM-5 or similarly behaving zeolite catalyst under hydrogen pressure followed by distillation of the product to remove light products such as naphtha, LPG and No. 2 fuel oil therefrom.
