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.
