CATALYTIC REMOVAL OF CARBON-MONOXIDE FROM GASES AT LOW-TEMPERATURES

A study was made of the low-temperature oxidation of carbon monoxide u sing both heavy catalysts (manganese oxide, manganese-palladium, manga nese-silver, hopcalite), and catalysts deposited onto mordenite (manga nese oxide, cobalt oxide, palladium). It was found that when carbon mo noxide reacted with atmospheric oxygen at room temperature the cobalt oxide and palladium catalysts deposited on mordenite were considerably more active than hopcalite, even in the presence of water vapor. By i ntroducing small quantities of ozone into the gaseous reaction mixture it was possible to intensify the carbon monoxide oxidation process wi th these catalysts.
