The invention provides a titania-zirconia or a titania-zirconia-alumina catalyst base containing a system of metals, metal oxides or metal sulfides from Groups VIB, VIIB and VIII of the Periodic Table. Such catalyst are useful in the hydrodesulfurization and denitrogenation of hydrocarbon feed stocks and the saturation of aromatics contained therein.

Use of catalyst comprising titania and zirconia in hydrotreating

Catalyst for hydrotreating

Catalysts capable of desulfurizing organo-sulfur compounds particularly those normally found in petroleum compositions, such as thiophene, are prepared from metal-containing compounds of metals of Groups VIB and VIII of the Periodic Table on a refractory support or base. Of particular interest are catalysts containing components of cobalt and molybdenum oxides on alumina which preparation utilizes dimethyl sulfoxide (DMSO). The use of such catalysts provides increase of conversion rate-constants of desulfurization reactions. A process of treating the base and the base material obtained from such process are also disclosed herein.
