A hydrotreating catalyst composed essentially of a carrier having a Bronsted acid content of 50 mu mol/g or above, e.g., one comprising silica, alumina and, if necessary, other components in which the silica is highly dispersed and which has a Bronsted acid content of 50 mu mol/g or above, and at least one active component selected from among group 8 elements of the periodic table and at least one active component selected from among group 6 elements thereof which are supported on the carrier; and processes for hydrotreating hydrocarbon oil with the catalyst. The catalyst exhibits an excellent resistance to inhibition by hydrogen sulfide and a high desulfurization activity and can exert remarkable effects in the depth desulfurization of hydrocarbon oil having a high sulfur content, particularly a gas oil cut containing difficultly desulfurizable sulfur compounds. Further, the catalyst is extremely effective also in the hydrodenitrogenation, hydrocracking, hydrodearomatization, hydroisomerization and hydrorefining of hydrocarbon oil, and so on.
