Abstract

The disclosure concerns the demetalation and desulfurization of metal and sulfur containing petroleum oils, preferably those containing residua hydrocarbon components, through the use of a catalyst comprising a hydrogenating component composited on a refractory base, preferably an alumina, whose pores are substantially distributed over a narrow 100A to 200A diameter range, but also having at least about 5% of its pores of a diameter greater than 500A.
