Abstract
A carbon supported catalyst used for carbon monoxide oxidation is chemically modified by treating the activated carbon support with an oxidizing agent and/or a hydrophobic compound prior to impregnation with the catalyst mixture. The thus treated catalytic carbon is capable of oxidizing carbon monoxide in an air stream containing sulfur dioxide over an extended period of time.
