Patent ID: 8545694

Claim:
An aromatics saturation process for lube oil boiling range feedstreams comprising: a) contacting a lube oil boiling range feedstream having an initial boiling point of at least 315° C. and containing aromatics, and nitrogen, and organically bound sulfur contaminants with an aromatics saturation catalyst in the presence of a hydrogen-containing treat gas in a reaction stage operated under effective aromatics saturation conditions, wherein said aromatics saturation catalyst comprises: i) an inorganic, porous, non-layered, crystalline, mesoporous support material, wherein the support material has a framework comprising at least aluminum and silica, and wherein the ratio of silica to aluminum is about 25:1, to about 70:1, and the average pore diameter of the support material is about 23 to less than about 27 Å; and ii) a hydrogenation-dehydrogenation component selected from the Group VIII noble metals and mixtures thereof.
