Abstract:
1. A stationary source catalyst for use in a stationary source exhaust gas stream comprising an alkali component that comprises K, Ba, Mg, or combinations thereof and a transition metal that comprises manganese (Mn) both dispersed on a metal oxide support comprising ceria, the catalyst being substantially free from precious metal components and effective to substantially simultaneously oxidize ammonia (NH 3 ) and carbon monoxide (CO) when placed in the exhaust gas stream and being adapted for use in a turbine exhaust stream; wherein the total weight of the catalyst including the alkali component, the transition metal, and the metal oxide support comprises precious metals at a level of less than or equal to approximately 100 ppm, approximately 1% by weight of K, Ba, Mg expressed as an oxide, or combinations thereof and approximately 1 to 3% by weight of Mn expressed as an oxide.
