 1741.    ---------------.  [KEUNTZEL, W. E.]  Preferential Catalytic Oxidation of Carbon Monoxide in the Presence of Hydrogen.  II.  Activity of 2-Component Hopcalites.  Jour. Am. Chem. Soc., vol. 52, 1930, pp. 445-455; Chem. Abs., vol. 24, 1930, p. 2367.

       Of the influent CO 97-99% was oxidized by free O₂ with a commercial hopcalite as catalyst in a temperature range of 160°-196°.  The composition of the converted water gas used was:  CO, 1.3; O₂, 1.5; CO₂, 28.0; H₂, 49.0; and N₂, 20.2% in the presence of 3 vol. of steam.  The catalyst suffered a loss of O and of activity.  The rapid dissipation of the heat of reaction was of importance.  The steam acts to dissipate this heat and to inhibit the reduction of the catalyst.
