FIELD: gas treatment.
SUBSTANCE: invention relates to processes of removing carbon monoxide from gas mixtures containing, except hydrogen, carbon dioxide. This process is an important step for production of pure hydrogen or hydrogen-containing gas, e.g. in ammonia synthesis. Catalyst for removing carbon monoxide from hydrogen-containing gas represents permeable composite material containing combination of phases of catalytically active group VIII metal or their alloy, oxide-type carrier, and metallic copper or copper metal containing alloy, composite-forming grain size being less than 0.5 mm and permeability of composite exceeding 10-14 m2. Catalyst preparation procedure as well as processes of removing carbon monoxide from hydrogen-containing gas using it are also described.
EFFECT: increased activity and selectivity of catalyst.
