 1740.    KEUNTZEL, W. E.  Preferential Catalytic Oxidation of Carbon Monoxide in the Presence of Hydrogen.  I.  Activity of Two Water-Gas Conversion Catalysts, of Copper Oxide, of Manganese Dioxide, and of a Mixture of These Oxides.  Jour. Am. Chem. Soc., vol. 52, 1930, pp. 437-444; Chem. Abs., vol. 24, 1930, p. 2367.

        Preferential oxidation of CO by O₂ in the presence of H₂, CO₂, a large excess of steam and various catalysts has been studied.  An efficiency of 96% for 37 hr. was obtained with a 2-component hopcalite.  Promoted Fe oxide and Co oxide governed only by the water-gas reaction CO+H₂O=CO₂+H₂.  CuO, MnO₂, and a 5-component hopcalite were catalytically active but suffered reduction and loss of activity.
