ABSTRACT:
A catalyst containing an overlayer of a catalytic promoter on a porous refractory support containing an underbedded phosphorus-containing component. The catalyst is prepared by incorporation and calcination of phosphorus with the porous refractory oxide support followed by further incorporation of the overlayer of catalytic promoter components, such as Group VIB and Group VIII metals. The catalyst is especially active when underbedded phosphorus components are incorporated into the support at calcination temperatures less than 900.degree. F. The catalyst is useful for simultaneous hydrodenitrogenation and hydrodesulfurization of a gas oil, particularly when the refractory oxide support has a narrow pore size distribution.
