Patent ID: 7682502

Claim:
An aromatics hydrogenation process for lube oil boiling range feedstreams comprising: contacting a lube oil boiling range feedstream containing aromatics and nitrogen and organically bound sulfur contaminants with a hydrogenation catalyst in the presence of a hydrogen-containing treat gas in a reaction stage operated under effective aromatics hydrogenation conditions to produce a reaction product with reduced aromatics content, wherein said hydrogenation catalyst comprises: i) an inorganic, porous, non-layered, crystalline, mesoporous support material; ii) at least one hydrogenation-dehydrogenation component selected from the Group VIII noble metals, wherein the average pore diameter of the support material is about 15 to less than about 40 Å and iii) a binder material wherein the support material and the binder material are composited in a ratio of support material to binder material ranging from about 65 parts support material to 35 parts binder material to 35 parts support material to 65 parts binder material, all ratios being by weight.
