Catalytic process for manufacture of lubricating oils

Patent ·
OSTI ID:5997841
;
A method is disclosed for converting an asphalt-free heavy hydrocarbon oil to high V.I. low pour point lube base stock and naphtha. The heavy oil is first catalytically dewaxed with a catalyst such as ni-zsm-5 and the dewaxed oil is then hydrocracked, or hydroconverted with a large pore zeolite catalyst such as dealuminized Y or zsm-20 associated with palladium. The V.I. is controlled by the severity of the hydroconversion step.
