A catalyst containing an overlayer of a catalytic promoter on a porous refractory support containing an underbedded Group VIII metal-containing component. The catalyst is prepared by sequential incorporation of the Group VIII metal followed by the additional catalytic promoter component, usually a Group VIB metal, with the porous refractory oxide support. The catalyst has a MoO. sub. 3 /NiO weight ratio less than 6 to 1 and more than 4 weight percent of NiO. The catalyst is especially useful for simultaneous hydrodenitrogenation and hydrodesulfurization of a gas oil, particularly when the refractory oxide support has a narrow pore size distribution.

Highly active cobalt-molybdenum-alumina desulfurization catalysts containing 18-30 weight-percent of MoO. sub. 3 are prepared by first comulling boehmite alumina with aqueous ammonium molybdate solution, drying the resulting mixture, then comulling with a soluble cobalt salt and water, thereafter forming the resulting mixture into extrudates, and finally calcining the extrudates under controlled temperature conditions correlated with the molybdenum content of the catalyst so as to preserve adequate surface area and prevent the formation of large crystallites of cobalt molybdate. This method of preparation permits effective utilization of molybdenum in amounts up to about 30 weight-percent MoO. sub. 3, a result not obtainable by conventional impregnation techniques.

A hydrocarbon conversion catalyst containing a Group VIB metal on a porous refractory oxide is prepared by impregnating support particles with a solution containing Group VIB metal components and citric acid, followed by drying and calcining. The catalyst is useful for promoting a number of hydrocarbon conversion reactions, particularly those involving hydrogenative desulfurization, demetallization and denitrogenation.

Novel, high surface area cobalt-molybdenum-alumina desulfurization catalysts containing 20-30 weight-percent of MoO. sub. 3, and being free of X-ray-detectable cobalt molybdate crystallites, are disclosed. A preferred method of preparation thereof involves first comulling boehmite alumina with aqueous ammonium molybdate solution, drying the resulting mixture, then comulling with a soluble cobalt salt and water, thereafter forming the resulting mixture into extrudates, and finally calcining the extrudates under controlled temperature conditions correlated with the molybdenum content of the catalyst so as to preserve adequate surface area and prevent the formation of large crystallites of cobalt molybdate.
