A process of recovering Cl2 from a stream of HCl includes the steps of providing a first fluidized bed of a carrier catalyst CuO in a first reaction zone; supplying HCl in a first stream to that zone for reaction with CuO in the bed to produce CuCl2, H2O and heat, removing CuCl2 from the zone in a second stream, removing H2O from the zone and removing heat from the zone; feeding the second stream to a second reaction zone, and providing a second fluidized bed of CuCl2 in the second reaction zone; and supplying O2 in a third stream to the second zone for reaction with CuCl2 in the second bed at elevated temperature to produce CuO and Cl2, removing Cl2 from the second zone in a fourth stream, and removing CuO from the second bed for re-use as a catalyst to produce CuCl2. |
