Abstract (en)

[origin: WO2007004774A1] Disclosed herein are an ammonia oxidation catalyst and a system for treating slipped ammonia or waste ammonia using the oxidation catalyst. More specifically, disclosed are an ammonia oxidation catalyst comprising either Cu-containing zeolite impregnated with platinum or Cu-containing alumina impregnated with platinum, which has improved low-temperature activity to oxidize ammonia generated in a mobile source or fixed source system and is used to inhibit the formation of nitrogen oxides, as well as a system for treating ammonia contained in vehicle exhaust gas, a chemical reactor system and an environmental device and system, which include the oxidation catalyst.
