    摘要: The present invention relates to a Selective Catalytic Reduction (SCR) catalytic converter that does not require the injection of a reducing agent, and, particularly, to an open-flow type or wall-flow type SCR catalytic converter that does not require the injection of a reducing agent, which includes a front portion, in which first supports supporting modified catalyst components are applied on the inner surfaces of porous partition walls, a middle portion, in which second supports supporting ammonia synthesis catalyst components are applied on the inner surfaces of porous partition walls, and a rear portion, in which third supports supporting SCR reducing catalyst components are applied on the inner surfaces of porous partition walls. More particularly, the present invention relates to a catalytic converter, which can improve a reduction rate of NOx without requiring the injection of an ammonia reducing agent from the outside.

    摘要: 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.
