Abstract
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.
