ABSTRACT OF THE DISCLOSURE Hydrotreating catalysts arc prepared using multiple impregnation and a critical ratio of VIB metal to VIII metal in one or more stages to produce catalysts which have higher than normal activity in contaminant removal from hydrocarbon feed stocks, especially in both sulfur and nitrogen removal. These catalysts also contain relatively low or no acidic residues such as P2O5 and permit the use of lower effective operating temperature for a predetermined percentage of contaminant removal, for example, at 85% removal of sulfur.
