Abstract
Abstract 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 and VIII of the Periodic Table. Such catalysts are useful in the hydrodesulfurization and denitrogenation of hydrocarbon feed stocks and the saturation of aromatics contained therein.
