Abstract: A PROCESS FOR PRODUCING ELECTRODE GRADE COKE FROM HIGH SULFUR AND METAL CONTAINING HYDROCARBON RESIDS COMPRISING THE STEPS OF (1) HEATING THE RESID AT 325-375*C. IN THE PRESENCE OF FINELY DIVIDED SODIUM AND UNDER NITROGEN OR HYDROGEN PRESSURE OF ABOUT 1500 P.S.I.G. FOR 1-3 HOURS, (2) WASHING THE SODIUM TREATED MATERIAL WITH WATER AND CO2 AT ELEVATED TEMPERATURE, (3) DEASPHALTING THE WASHED MATERIAL BY AN ALIPHATIC HYDROCARBON EXTRACTION TO YIELD A PERTOLEUM FRACTION LOW IN SULFUR AND METALS, AND (4) COKING SAID PETROLEUM FRACTION TO OBTAIN AN ELECTRODE GRADE COKE.
