Abstract

Method for removal of carbon monoxide from air wherein air to be purified is passed through a catalyst for promotion of oxidation of carbon monoxide consisting of a carrier including powdered activated carbon, an alkali, and a bonding agent and inpregnated with palladium alone or in combination one or more of the elements ruthenium, rhodium, and platinum. The amount of included alkali is made such that there is reduced risk of combustion due to presence of activated carbon, and the bonding agent renders the catalyst more resistant to vibration, while high rates of carbon removal are achieved at comparatively low temperature and high rates of air flow through the catalyst.
