Abstract
The present invention is drawn to a process for the production of anode grade coke from a hydrocarbon feed characterized by high levels of sulfurs and metals. The hydrocarbon feed is hydrocracked in a hydrocracking reactor so as to produce an overhead effluent which is fed to a hot separator wherein a light hydrocarbon stream and a slurry hydrocracked product are produced. The hydrocracked product is fed to a separator and mixed with a solvent wherein the solids are separated out from the hydrocracked residual so as to produce a clean hydrocracked residual which is fed to a coking drum and coked so as to leave a mass of green anode grade coke.
