ABSTRACT:
Catalysts, catalyst systems, and methods for removing ammonia and/or carbon monoxide in flue gases are provided where ammonia is used with a selective catalytic reduction catalyst for reducing oxides of nitrogen. An oxidation catalyst is utilized, which comprises particulate platinum or platinum/palladium dispersed on zirconia particles, the particulate platinum or platinum/palladium having an average particle size less than about 10 nm. The catalyst is effective to convert less than 20% of NO to NO2passing through the oxidation catalyst.
