  • Patent number: 4435274
    Abstract: Residual oils from steam-cracking or catalytic cracking, oils from coal liquefaction and oils from bituminous sands and shales are converted to gasoline by a process comprising the fractionation of the feed charge to a naphtha and a middle distillate: the naphtha, admixed with a gasoline cut "E", is hydrotreated and then dehydrogenated to gasoline; the middle distillate is hydrotreated and fractionated to gasoline and a heavier fraction, the heavier fraction is hydrocracked and fractionated, thus producing a gasoline cut which constitutes the above cut "E".
