Abstract
A hydroprocess catalyzed by a catalyst composition comprising a porous refractory oxide, a molybdenum component, a phosphorus component and an underbedded nickel component, the composition characterized by a Raman spectrum comprising at least one Raman band in each of the regions of (1) about 240 cm.sup.-1 to about 250 cm.sup.-1, and (2) about 595 cm.sup.-1 to about 605 cm.sup.-1. The catalyst is prepared by sequential incorporation of the nickel metal followed by the additional catalytic promoters including a molybdenum component and a phosphorus component.
