THE OXIDATION OF CARBON MONOXIDE BY SOLID SILVER PERMANGANATE REAGENTS: II. KINETIC STUDIES WITH SILVER PERMANGANATE – ZINC OXIDE

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 gener...
