Abstract: A process for producing chlorine comprises the steps of oxidizing hydrogen chloride in the presence of a catalyst in an oxidation reactor, passing the product gas together with the catalyst removed from the oxidation reactor to a high velocity transporter at a temperature between 150-250.degree. C. to remove the residual HCl from the product gas, removing the catalyst from the product and recycling the removed catatalyst back to the oxidation reactor.

Abstract: A diffusion process from steam reforming of a hydrocarbon to produce H.sub.2, Co and CO.sub.2, that includes: providing a generally tubular, porous, ceramic membrane, and providing a heated reaction zone in a container into which the membrane is received; the membrane carrying a catalytically active metallic substance; passing a hydrocarbon and steam containing first fluid stream into the zone and into contact with one side of the membrane, to produce CO, CO.sub.2 and H.sub.2 ; and passing a second fluid stream adjacent the opposite side of the membrane in such manner as to promote hydrogen diffusion through the membrane from said one side to said opposite side thereof; and removing hydrogen from the opposite side of the membrane. Such a process may be combined with operation of a heat engine or gas turbine, producing heat transferred to the referenced reaction zone.

Abstract: A process of recovering chlorine from a stream of hydrocarbon chloride includes providing a first fluidized bed of a carrier catalyst cupric oxide in a first reaction zone within a first reactor; supplying hydrogen chloride in a first stream to that first zone for fluidizing the first bed and for exothermic reaction with cupric oxide in the bed to produce cupric chloride, water and heat, removing cupric chloride from that zone in a second stream, and removing water from that zone and removing heat from that zone; feeding the second stream to a second reaction zone within a second reactor, and providing a second fluidized bed of cupric chloride in the second reaction zone, and; supplying oxygen in a third stream to the second zone for fluidizing the second bed and for endothermic reaction with cupric chloride in the second bed at elevated temperatures between 300.degree. and 360.degree.
