A stabilized lubricating oil resistant to oxidation and sludge formation upon exposure to an oxidative environment is prepared without forming undesirable color bodies therein by the steps (1) contacting the lubricating oil stock with a small amount of added elemental sulfur of from about 0. 05 to about 1. 0 percent by weight at a contact temperature of from about 25. degree. C. to about 130. degree. C. and (2) contacting the product of step (1) with hydrogen in the presence of alumina impregnated with at least about 10 weight percent MoO. sub. 3 and at least about 2. 5 weight percent CoO to remove any unreacted added elemental sulfur therefrom. The impregnated alumina catalyst of step (2) must have at least 50 percent of the pores with a pore diameter of 50 Angstrom Units or more.

Improved catalytic hydrodewaxing of gas oil fractions using as the catalyst a high silica to alumina ratio crystalline aluminosilicate zeolite having shape selective properties for normal and mono methyl configuration paraffins, by using as the catalyst such a zeolite having a multi-valent transition metal and a Group VIII noble metal incorporated therewith.

The present invention provides a process for catalytic upgrading of refractory hydrocarbon charge stocks, such as coker gas oil, to premium products including gasoline, kerosene, diesel fuel and low sulfur cracking stock initially by catalytic hydrotreating and cascading the hydrotreater effluent, through a hydrocracking zone, without change in the pressure of the system, containing a catalyst which is characterized by a crystalline zeolite having a silica/alumina ratio greater than 12 and a constraint index of 1 to 12.

Liquid products from retorting oil shale are upgraded to a total liquid suited to pipeline transport and containing increased amounts of the premium products gasoline through distillate fuel by hydrotreating to convert sulfur, oxygen, nitrogen and metal constituents and cascading the hydrotreater effluent through a hydrocracking reactor containing a catalyst which is characterized by a crystalline zeolite having a silica/alumina ratio greater than 12 and a constraint index of 1 to 12, for example zeolite ZSM-5.

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.

A stabilized lubricating oil resistant to oxidation and sludge formation upon exposure to an oxidative environment is prepared without forming undesirable color bodies therein by contacting the lubricating oil stock with a small amount of elemental sulfur of from about 0. 1 to about 0. 5 percent by weight at a contact temperature of from about 25. degree. C to about 70. degree. C and, thereafter, removing any unreacted sulfur therefrom.

A catalyst effective in hydrotreating and hydrocracking sulfur- and nitrogen-containing hydrocarbon feeds at low pressure. The catalyst is prepared by incorporating a platinum group metal such as palladium in ZSM-20 or in dealuminized zeolite Y. Unlike most palladium catalyst, this catalyst is not poisoned by nitrogen and sulfur in the feed.
