Abstract (en)
[origin: WO9829340A1] The recovery of aluminum chloride from deactivated alkylation catalyst complexes by hydrogenation using hydrogen gas (22) 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 (18) thus reducing the corrosiveness and cost of the aluminum chloride recovery. Methods for batch, batchwise-continuous, and continuous aluminum chloride recovery are disclosed.
