Zusammenfassung:An embodiment of the present invention provides a fluidized-bed SCR catalytic reactor for reducing nitrogen oxide and a method for reducing nitrogen oxide using the same. A fluidized bed of the fluidized-bed SCR catalytic reactor improves the contact efficiency between exhaust gas and a SCR catalyst, a flow controller actively controls a flow rate according to the concentration of nitrogen oxide, and the input amount of catalyst is controlled through catalyst particles having different surface areas so as to improve the processability of nitrogen oxide. 본 발명의 일실시예는 질소산화물 저감을 위한 유동층 SCR 촉매 반응기, 및 이를 이용한 질소산화물 저감 방법을 제공한다. 상기 유동층 SCR 촉매 반응기의 유동층에 의해 상기 배기가스와 SCR 촉매의 접촉 효율이 향상되고 유량조절기에 의해 질소산화물의 농도에 따라 유동 속도가 능동적으로 조절되고 표면적이 다른 촉매 입자를 통해 촉매 투입량을 조절하여 질소산화물 처리능력을 향상 시킬 수 있는 효과가 있다.
