Abstract
A catalyst suitable for mild-hydrocracking of cracked petroleum hydrocarbon feedstocks and selective to diesel fuels contains a catalytically active metal phase constituted by a Group VI-B element, a Group VIII first transition series element and a Group VIII second transition series element, all supported on a titania-alumina support containing about 5% to about 30% by weight titania in the support. The support is prepared by combining titanium oxide and aluminum oxide hydrogels, in appropriate proportions, followed by extrusion, drying, and calcination. The catalytically active metal phase is introduced onto the support by impregnation followed by drying and calcination. The catalytically active metal phase is then sulfided. The produced catalyst is suitable for hydrodesulfurization, hydrodenitrogenation, mild-hydrocracking and aromatics hydrogenation of previously cracked petroleum hydrocarbon feedstocks.
