An aromatics hydrogenation catalyst composition which comprises a noble
metal component and a support comprising zirconia, silica, and,
optionally, alumina. The catalyst composition is manufactured by
co-mulling silica, a zirconium compound, and, optionally, alumina to form
a mixture that is formed into a shape, such as by extrusion to form an
extrudate, with the shape being calcined and noble metal being
incorporated into the shape. The catalyst composition may be used in the
saturation of aromatic compounds.
