METHOD AND DEVICE FOR REDUCTION OF CARBON MONOXIDE CONCENTRATION AND CATALYST FOR SELECTIVE OXIDATION OF CARBON MONOXIDE Russian patent published in 2002 - IPC

FIELD: selective reduction of carbon monoxide concentration. SUBSTANCE: device has source of gas rich in hydrogen and source of oxidizing gas. Reaction of selective oxidation of carbon monoxide is conducted in presence of catalyst. It contains ruthenium as primary component and alkaline or alkaline-earth metal as additional component. Alkaline or alkaline-earth metal is used in the form of simple mass of metal or in the form of alloy with ruthenium, or ruthenium is used as primary component and nickel as additional one, ruthenium is used as primary component and zinc as additional component. EFFECT: extended range of efficient temperatures with preserved sufficiently high activity of selective reaction of carbon monoxide oxidation. 17 cl, 5 dwg
