The invention is a process for making anode grade coke which comprises solvent deasphalting a residue feedstock to obtain an essentially asphaltene-free, resin-containing stream and coking the resin-containing stream in a delayed coker to make anode coke. The solvent deasphalting can make a deasphalted oil stream containing resin or separate deasphalted oil and resin streams. There can be hydrotreating of (1) a minor portion of the residue feedstock wherein the hydrotreated residue is fed to the delayed coker with the resin-containing stream, (2) the resin-containing stream wherein the hydrotreated resin stream is fed to the delayed coker, or (3) a major portion of the residue feedstock wherein the hydrotreated residue is fed to the solvent deasphalting unit.

The recovery of aluminum chloride from deactivated alkylation catalyst complexes by hydrogenation using hydrogen gas and an aluminum catalyst is disclosed. Using aluminum to catalyze the hydrogenation allows the reaction to proceed at a lower temperature and pressure while reducing the amount of hydrogen chloride present in the reactor thus reducing the corrosiveness and cost of the aluminum chloride recovery. Methods for batch, batchwise continuous, and continuous aluminum chloride recovery are disclosed.
