NO Reduction by CH₄ over NiCo/MOR Catalysts in the Presence of Oxygen

Abstract:

The Ni(x)Co(10)/MOR (x = 0.01, 0.15, 0.30) catalysts were prepared by the impregnating method. The catalysts were characterized by XRD, NH₃-TPD and NO-TPD. The catalytic activity was evaluated with fixed-bed reactor. The results shown that cobalt species was present in the surface of MOR zeolite in the form of Co3O4, and the catalytic activity, acidity and adsorption of NO were affected by Ni/Co molar ratio. The Ni(0.01)Co(10)/MOR catalyst had better activity, the conversion of NO was 56.9% at 340 °C.
