ABSTRACT:
A process is described for the simultaneous demetalization and hydrocracking of heavy hydrocarbon oils. The process permits the recovery of metals such as vanadium and nickel in an economic manner by passing a slurry of a heavy hydrocarbon oil and carbonaceous additive particles, such as coal, in the presence of hydrogen through a confined vertical hydrocracking zone at high temperatures and pressures. A mixed effluent containing a gaseous phase and a liquid phase is removed from the top of a hydrocracking zone, while there is removed from the bottom of the hydrocracking zone a portion of the hydrocracking zone contents containing carbonaceous remains of the additive particles to which is adsorbed the metal residues from the feedstock. The effluent removed from the top of the hydrocracking zone can be subsequently fed directly to a catalytic hydrocracking unit.
