Patent ID: 8425762

Claim:
An aromatics hydrogenation process for a hydrocarbon feedstream comprising: a) contacting a hydrocarbon feedstream that contains aromatics with a hydrogenation catalyst in the presence of a hydrogen-containing treat gas in a first reaction stage operated under effective aromatics hydrogenation conditions, the effective aromatics hydrogenation conditions comprising a temperature of about 190° C. or less, wherein said hydrogenation catalyst comprises: i) an inorganic porous crystalline phase material comprising MCM-41 and having, after calcination, a hexagonal arrangement of uniformly-sized pores having diameter of at least about 15 Angstroms to about 25 Angstroms and exhibiting a hexagonal diffraction pattern that can be indexed with a d 100 value greater than about 18 Angstroms, wherein the inorganic porous crystalline phase material contains SiO 2 and XO 2 , where X is selected from Ti, Zr, or a combination thereof, and the inorganic porous crystalline phase material is formed from a synthesis mixture having a ratio of SiO 2 :XO 2 of about 100:1 or less, and (ii) at least one hydrogenation-dehydrogenation component selected from the Group VIII noble metals.
