ABSTRACT:
In the catalytic hydroprocessing of hydrocarbons, a hydrocarbon oil is successively contacted with a first hydroprocessing catalyst in a first reaction zone and a second hydroprocessing catalyst in a second reaction zone. The first catalyst has an average pore diameter at least about 30 angstroms larger than the second catalyst, although both have narrow pore size distributions wherein at least about 90 percent of the total pore volume is in pores of diameter from about 100 angstroms to about 300 angstroms, and with essentially all the pores having diameters greater than 100 angstroms.
