Abstract

A composition comprises a hydrogenation catalyst supported on an inorganic support which comprises aluminum, zirconium, and a borate. A process for producing the composition comprises the steps of (1) contacting an aluminum salt, a zirconium salt, and an acidic boron compound under a condition sufficient to effect the production of a solid material comprising aluminum, zirconium, and borate; and (2) combining a hydrogenation catalyst with the inorganic support. Also disclosed is a process for reducing aromatic compounds content in a hydrocarbon-containing fluid which comprises contacting a hydrocarbon-containing fluid, in the presence of a catalyst composition, with hydrogen wherein said catalyst composition comprises a hydrogenation catalyst and an inorganic support wherein said support comprises aluminum, zirconium and a borate.
