Heavy oils may be hydrotreated in the presence of a porous alumina support bearing metals of Group VIII and VI-B and optionally phosphorus, the catalyst having a Total Surface Area of 165-230 m2/g, a Total Pore Volume of 0.5-0.8 cc.g, and a Pore Diameter Distribution whereby less than about 5% of th

Heavy oils may be hydrotreated in the presence of a porous alumina support bearing metals of Group VIII and VI-B and optionally phosphorus, the catalyst having a Total Surface Area of 165-230 m2/g, a Total Pore Volume of 0.5-0.8 cc.g, and a Pore Diameter Distribution whereby less than about 5% of the Total Pore Volume is present as primary micropores of diameter less than 80Å, and secondary micropores of diameter of ±20Åof a Pore Mode of 100-135Åare present in amount of at least about 65% of the micropore volume having pores with diameter less than 250Å, and 22-29% of the Total Pore Volume is present as macropores of diameter >250Å. The process of the instant invention is particularly effective in achieving desired levels of hydrodemetallation, hydrodesulfurization, and hydrocracking of asphaltenes in the fraction of hydrotreated/hydrocracked petroleum resid product having a boiling point greater than 1000°F.

A process for hydrotreating a charge hydrocarbon fuel containing components boiling above 1000°F., and sulfur, metals, and asphaltenes which comprises contacting said charge hydrocarbon feed with hydrogen at isothermal hydrotreating conditions in the presence of, as catalyst, a porous alumina support bearing 3.0-3.5% NiO, 14.5-16.5% MoO3, and 0.2 w % of P2O5, said catalyst having a Total Surface Area of 165-230 m2/g, a Total Pore Volume of 0.73-0.8 cc/g, and a Pore Diameter Distribution whereby 0-3% of the Total Pore Volume is present as primary micropores of diameter less than about 80 Å, and secondary micropores having diameters ±20 Åof a Pore Mode of 105-125 Åare present in amount of at least about 65% of the micropore volume having pores with diameter less than 250 Å, and 25-29% of the Total Pore Volume is present as macropores of diameter greater than about 250 Å, thereby forming hydrotreated product containing decreased contents of components boiling above 1000°F., sulfur, metals, and asphaltenes; and recovering said hydrotreated product containing decreased contents of components boiling above 1000°F., sulfur, metals, and asphaltenes.
