The invention relates to a cyclic method of producing a hydrogen rich and/or a carbon monoxide rich stream using different materials, a first solid material, a second solid material and a CO.sub.2 sorbent material.

In a first step a first gas stream comprising steam and at least one reductant is brought in contact with the three materials resulting in a hydrogen rich outlet stream.

In a second step, the captured CO.sub.2 from the first step is released and converted to CO to produce a CO rich outlet stream.

The invention further relates to an installation for producing a hydrogen rich and/or carbon monoxide rich stream.

The present invention relates to a molding catalyst and a method for producing the same, wherein the molding catalyst is used in the Deacon process for commercial production of chlorine using hydrogen chloride oxidation reaction, exhibits only a small reduction in catalytic activity even when exposed to harsh reaction conditions to thus be durable, and has superb mechanical strength to be suitable for use in a fixed bed catalytic reactor.
