Simultaneous demetalization and hydrocracking of heavy hydrocarbon oils

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