Studies on the Removal of Carbon Monoxide From the Atmosphere at Ambient Temperature.
Abstract
Catalysts of platinum or palladium on carbon or alumina show much promise in removing carbon monoxide (CO) from air at room temperature. As much as 80% of the CO in a 230 ppm CO/air mixture was removed by 1 g of 5% palladium on carbon powder in one pass. Catalysts of 0.5% metal on alumina pellets showed comparable efficiency, and proved much more convenient to handle. Calculations indicate that the CO concentration in 1000 cu ft of air containing 500 ppm CO could be reduced to 200 ppm in 100 minutes using only 180 g (0.4 pound) of 0.5% palladium catalyst and a pump moving 10 cu ft per minute of air (one pass of air through catalyst). Solutions of copper(I) in monoethanolamine proved much less efficient due to oxidation problems. (Author)
