ABSTRACT:
A catalyst comprises an alumina carrier having a surface concentration as measured by X-Ray Photoelectronic Spectroscopy (XPS) to give values of the Group VIB metal Xs/(A1+X)s of between 4 to 15 where X equals the Group VIB metal and a bulk concentration of between 2.0 to 15.0 wt. % of said Group VIB metal, a surface concentration as measured by X-Ray Photoelectronic Spectroscopy (XPS) to give values of the Group VIII metal Ys/(A1+Y)s of between 2 to 5 where Y equals the Group VIII metal and a bulk concentration of between 1.0 to 4 wt. % of said Group VIII metal, a surface concentration as measured by X-Ray Photoelectronic Spectroscopy (XPS) to give values of phosphorus Ps/(A1+P)s of between 0.1 to 8 and a bulk concentration of between 0.4 to 2 wt. % phosphorus and a surface concentration as measured by X-Ray Photoelectronic Spectroscpy (XPS) to give values of silica SiO.sub.2 /(A1+SiO.sub.2) of between 1 to 10 and a bulk concentration of between 0.1 to 5 wt. % silica and a process for the conversion of heavy hydrocarbon feeds employing said catalyst.
