ABSTRACT:
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 m.sup.2 /g, a Total Pore Volume of 0.5-0.8 cc.g, and a Pore Diameter Distribution whereby less than about 5% the Total Pore Volume is present as primary micropores of diameter less than 80 .ANG., and secondary micropores of diameter of +20 .ANG. of a Pore Mode of 100-135 .ANG. are present in amount of at least about 65% of the micropore volume having pores with diameter less than 250 .ANG., and 22-29% of the Total Pore Volume is present as macropores of diameter >250 .ANG..
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.degree. F.
