Abstract: A process is provided for the desulfurization of residual oil by(a) separating the residual oil into a first and a second fraction;(b) reacting the first fraction with hydrogen over a hydrodesulfurization catalyst in a first reaction zone at hydrodesulfurization conditions such that a liquid effluent of lower sulfur content than the residual oil is obtained;(c) combining the hydrodesulfurization liquid effluent with the second residual oil fraction; and(d) reacting the resultant mixture over a hydrogenation/dehydrogenation catalyst in a second reaction zone at hydrogen transfer conditions.This process provides for desulfurization of residual oils at lower hydrogen consumptions than conventional processes.

Abstract: A zeolite catalyst suitable for use in shape-selective hydrocarbon conversion processes. The catalyst is modified by incorporation therein of a hydrogenation-dehydrogenation functional metal, followed by gradient selectivation with an organosilicon compound under conversion conditions, wherein the gradient selectivation conditions are characterized by a progressive temperature gradient. The use of a progressive temperature gradient during the in situ selectivation procedure unexpectedly yields a catalyst in which the hydrogenation-dehydrogenation function is stabilized, thereby enabling long duration hydrocarbon conversion processes with low by-product make.

Abstract: There is provided a method for preparing an acidic solid oxide having a reduced particle density, where the acidic solid oxide comprises a Group IVB metal oxide modified with an anion or oxyanion of a Group VIB metal. An example of this acidic solid oxide is zirconia modified with tungstate. The acidic solid oxide having a reduced particle density is prepared by coprecipitating the Group IVB metal oxide along with the anion or oxyanion of the Group VIB metal in the presence of a salt. This acidic solid oxide is particularly effective as a paraffin isomerization catalyst.
