Claim Text:
1. A process for upgrading residuum hydrocarbon feedstocks, comprising: contacting a residuum hydrocarbon and hydrogen with a hydroconversion catalyst in an residuum hydroconversion reactor system; recovering an effluent from the residuum hydroconversion reactor system; separating the effluent from the residuum hydroconversion reactor system to recover two or more hydrocarbon fractions including at least a vacuum residuum fraction and a heavy vacuum gas oil fraction; combining at least a portion of the heavy vacuum gas oil fraction and at least a portion of the vacuum residuum fraction to form a mixed heavy hydrocarbon fraction; feeding at least a portion of the mixed heavy hydrocarbon fraction to a coker; operating the coker at conditions to produce anode grade green coke and distillate hydrocarbons; recovering the distillate hydrocarbons from the coker; fractionating the distillate hydrocarbons recovered from the coker to recover three or more hydrocarbon fractions including a light distillates fraction, a heavy coker gas oil fraction, and a coker recycle fraction, wherein the said vacuum residuum feedstock is derived from one or more of Arab Heavy, Arab Light, Banoco Arab Medium, Kuwait Export, Basrah Light, Rubble, Bahrain, Oman, Upper Zakam, REBCO, Kumkol, Azeri Light, Siberian Light, Siberian Heavy, and Tengiz petroleum crude oils.
