Abstract: A hydrogenation process for reducing the unsaturation of lubricants uses a catalyst which is based on an ultra-large pore crystalline material. The crystalline material has pores of at least 13 .ANG. diameter arranged in a uniform manner and exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams (50 torr and 25.degree. C.). A preferred form of the catalyst has a hexagonal structure which exhibits a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 .ANG.. The hydrogenation catalysts based on these materials are capable of reducing the unsaturation in poly alpha olefin lubricants to a low level.

Abstract: A process for significantly decreasing the acid sludge settling time in waste oil recovery processes comprising the steps of heating used oil to a high temperature above 725 degrees Fahrenheit, cooling the heated oil, adding an oxidizing agent to the oil, allowing the acid sludge to settle within a period of approximately 24 to 72 hours, separating the acid-sludge-free oil from the acid sludge which settles out of solution as a result of addition of the oxidizing agent, and adding a polishing agent and separating the re-refined oil from the spent polishing agent. The spent polishing agent is recycled, and the acid sludge which settles out after oxidation is converted to either hard, oxidized asphalt or soft asphalt or asphalt products such as emulsions etc. The process produces a high quality re-refined oil rapidly and economically with no acid sludge disposal problem.

Sufficiently desulfurized hydrocarbons are obtainable by allowing the catalyst compositions to contact sulfur-containing hydrocarbons in the presence of hydrogen.

Abstract: A catalytic reforming process uses a riser reactor with multiple catalyst injection points to obtain high aromatics yields from a naphtha feedstock. Product from the riser reactor typically is discharged into a fluidized-reforming reactor, in which the reforming reaction is completed and catalyst is separated from hydrogen and hydrocarbons. Hydrocarbons from the reactor are separated to recover an aromatized product. Catalyst is regenerated to remove coke and reduced for reuse in the reforming process.
