Patent GB-924293-A (GB)
Title: Improvements in or relating to process for manufacturing mixtures of hydrogen, carbon monoxide and/or methane
IPC: C10K3/00
Filed: 1959-06-22
Abstract: A mixture of hydrogen, carbon monoxide and a variable amount of methane is produced by passing a stream of solid comprising at least one iron oxide or a mixture thereof with metallic iron downwards through a reduction zone in countercurrent to a gas comprising carbon monoxide, passing the reduced iron product (containing iron and/or iron carbide) downwards through an oxidation zone under superatmospheric pressure in countercurrent to steam alone or a mixture of steam and carbon dioxide, so as to produce the desired gas product, and recycling the oxidised iron to the reduction zone. Steam alone is used in the oxidation zone when the reduced iron product contains a substantial amount of carburised iron.  When the conditions are such that the gas product consists essentially of carbon monoxide and hydrogen, the solid may be passed downwards through a methanation zone between the reduction and oxidation zones in counter-current to the water-freed product to produce a final gas product comprising a high proportion of methane.  The temperature of solid at the bottom of the reduction zone may be 850 DEG -1750 DEG F. The carbon monoxide-containing gas used in the reduction zone may be a producer gas obtained by the partial oxidation of carbonaceous material with air, or a tail gas from a Fischer-Topsch unit.  A portion of the gaseous effluent from the reduction zone may be recycled thereto after removal of carbon dioxide and water.  The carbon dioxide removed may be passed to the oxidation zone.  All or a portion of the gaseous effluent from the reduction zone may be burnt to provide energy for the preheating and/or compression of air to be used in the production of the producer gas.  Air may be introduced into the upper portion of the reduction zone to effect combustion and increase in the temperature of the solid in the reduction zone.  The temperature of the solid at the top of the oxidation zone may be 950 DEG -1750 DEG F.  The pressure in the oxidation zone may be 150-500 psig.  Carbon dioxide may be removed from the gas product from the oxidation zone and recycled thereto.  Specification 725,000 is referred to.
