    • PURPOSE: A catalyst for simultaneous reduction of N2O and NOx and a method for manufacturing are provided to be used in not only the N2O and NOx single occurrence place of business but also a simultaneous occurrence place of business by reducing N2O and NOx at the same time in one selective catalytic reduction(SCR) reaction top. CONSTITUTION: A method for manufacturing a catalyst for simultaneous reduction of N2O and NOx comprises: a step of preparing zeolite; a step of dipping iron(Fe) in the zeolite; a step of dipping potassium(K) in the zeolite in which the iron(Fe) is dipped; and a step of drying and plasticizing the zeolite in which the iron(Fe) and potassium(K) are dipped. The zeolite is selected in a group consisting of pentasil(MFI) type zeolite, mordenite(MOR) type zeolite, clinoptilolite nature(NZ) zeolite and a mixture.
    • 目的:同时还原N2O和NOx的催化剂及其制造方法不仅可用于N2O和NOx单一发生地,而且可同时通过还原N2O和NOx同时发生。 在一个选择性催化还原(SCR)反应顶部。 构成:制造用于同时还原N 2 O和NO x的催化剂的方法包括:制备沸石的步骤; 在沸石中浸渍铁(Fe)的步骤; 将钾(K)浸入其中浸渍铁(Fe)的沸石中的步骤; 以及浸渍铁(Fe)和钾(K)的沸石的干燥和塑化步骤。 沸石选自pentasil(MFI)型沸石,丝光沸石(MOR)型沸石,斜发沸石性质(NZ)沸石和混合物。
