摘要： 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.

摘要： A tri-elemental catalyst on a support that includes a pentasil crystalline zeolite and is suitable for hydrocracking and hydrogenation of aromatics-containing petroleum hydrocarbon feedstocks such as hydrotreated cracked feedstock, virgin feedstock, vacuum distillate, middle distillate, mixtures thereof, and the like, is disclosed. The catalyst is suitable for hydrodesulfurization as well as hydrodenitrogenation, thus the feedstock can contain sulfur and nitrogen in addition to the aromatic components. Hydrocracking and aromatics hydrogenation of the petroleum hydrocarbon feedstocks is accomplished under a relatively wide range of process conditions in plural process zones using the tri-elemental catalyst that 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. In an upstream zone the catalytically active metal phase is supported on a titania-alumina support containing about 5% to about 30% by weight titania in the support. In a downstream zone the catalytically active metal phase is supported on a titania-alumina-pentasil crystalline zeolite support. The preferred pentasil crystalline zeolite is ZSM-5.
