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.
