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.

A process for the production of anode grade coke from a hydrocarbon feed characterized by high levels of sulfur and metals comprising feeding a hydrocarbon feed to a hydrocracking reactor; hydrocracking said hydrocarbon feed in said reactor under the following conditions: pressure about between 1000 to 4000 psi, LHSV of about between 0.2 to 3.0 HR-1, hydrogen-crude ratio of about between 3,000 to 40,000 SCF/B and temperature of about between 420°to 500°C. wherein an effluent overhead is produced; feeding said effluent to a hot separator; treating said effluent in said hot separator wherein a light hydrocarbon stream and a slurry hydrocracked product residual are produced; feeding said slurry hydrocracked product residual to a separator; mixing a solvent with said hydrocracked residual in said separator; separating out the solids from said hydrocracked solvent rich residual so as to produce a clean upgraded hydrocracked solvent rich residual with low sulfur and metals content; and feeding said upgraded hydrocracked residual to a coking drum wherein said residual decomposes leaving a mass of anode grade coke.
