Oxidation Of Carbon Monoxide

Copper zinc oxide catalysts are effective for the ambient temperature carbon monoxide oxidation and display higher specific activity than the current commercial hopcalite catalyst. We investigate the copper zinc oxide catalyst prepared by co-precipitation under different atmospheres for the oxidation of carbon monoxide at low temperatures and these systems are now worthy of further investigation.

Oxidation Of Carbon Monoxide

The kinetic equations of the adsorption wave were applied to the oxidation of carbon monoxide in an air stream by granular silver permanganate – zinc oxide reagent. The following relations have been investigated in this system: (a) the concentration of the escaping gas as a function of time, (b) the effect of initial concentration, column length, and flow rate on breakdown time, (c) the influence of granule size on breakdown time and rate of reaction. The critical column length was found to be dependent on flow rate and independent of initial concentration. Critical column lengths of approximately 0.4 cm. to 1 cm. were found for the range of flow rates studied. The relation found between granule size and breakdown time does not completely agree with the theoretical equations. As the mean diameters of the granules decreased from 2.2 mm. to 0.90 mm. the breakdown time increased, but a decrease in mean diameter from 0.90 to 0.30 mm. resulted in a reduction of breakdown time. Although the results are in general agreement with the equations developed by Hinshelwood and Klotz, certain deviations from the theoretical treatment were evident.
