Gatsis, J G

A process for the desulfurization and hydrocracking of a heavy hydrocarbon oil containing sulfur and asphaltenes, which comprises reacting said oil with hydrogen in a first reaction stage to desulfurize said oil, reacting the effluent from said first stage in a second reaction stage to hydrocrack and desulfurize the oil further, said first and said second reaction stages being carried out in contact with a supported catalyst composite comprising a metal from Group VI-B and a metal from Group VIII of the Periodic Table with alumina containing from about 10.0 percent to about 90.0 percent by weight of silica, said catalyst composite being characterized by having a macropore volume consisting of pores having pore diameters in the range of 117 to 58,000 Angstroms, less than 50 percent of the macropore volume of said catalyst in said first stage being characterized by pores having pore diameters greater than about 1000 Angstroms and more than 50 percent of the macropore volume of the catalyst in said second stage being characterized by pores having pore diameters greater than about 1000 Angstroms.
