Abstract
A process for upgrading residuum hydrocarbon feedstocks that may include: contacting a residuum hydrocarbon and hydrogen with a hydroconversion catalyst in a residuum hydroconversion reactor system; recovering an effluent from the residuum hydroconversion reactor system; separating the effluent 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 to recover hydrocarbon fractions including a light distillates fraction, a heavy coker gas oil fraction, and a coker recycle fraction.
