Abstract: This invention is directed to a catalyst composition effective in hydroprocessing and a process employing this catalyst. The catalyst composition comprises three acidic components acting in synergy to provide enhanced catalytic activity, when compared to any of the components alone or in combinations of two. Two of the components are large pore zeolites, and the third component is selected from the group comprising clays and amorphous silica/alumina.
