Abstract: Heavy hydrocarbon feed oils such as heavy gas oils, residium, topped crude oils and the like are hydrocracked by mixing hydrogen with the feed oil in the ratio of hydrogen to feed oil in the range from 4000 to 10,000 SCF of hydrogen per barrel of feed oil and contacting this mixture under hydro-treating conditions with a supported micro-spherical catalyst having 5-20 weight per cent tungsten and 0.5 to 5.0 weight per cent rhenium. Increased isoparaffin and aromatic content in the cracked product is obtained.

Abstract: Process for the hydrogenation of heavy hydrocarbon residues boiling in the range from about 220* F to about 650*F and containing up to 10 percent by weight of tars and gums wherein the hydrocarbon is mixed with hydrogen, passed through a hydrogenation zone under a pressure of 100-1,000 psig, a temperature of 100*C to 200*C, and in the presence of a supported platinum or palladium catalyst and cooled. The hydrogenated product is then distilled to produce a high grade gasoline blend stock as the overhead and the bottoms are useful as a fuel oil.
