Abstract
Heavy hydrocarbon oils are converted into light hydrocarbon oils by two-stage process wherein, in the first stage, a heavy hydrocarbon oil is subjected to thermal cracking conditions and, in the second stage, the product of the thermal cracking is subjected to a hydrotreatment in the presence of a specific catalyst having a large pore volume in pores with diameters of 200-400 .ANG.. The hydrotreatment is carried out so that the product oil may have a toluene insoluble content of 0.5 wt % or less.
