Selective catalytic reduction of NO_x with methane over M/MOR (M=Mn, Fe, Ni) in the presence of oxygen

摘要

The catalysts, M (10)/MOR (M=Mn, Fe, Ni), were prepared by impregnation methods and characterized by XRD, NH_3-TPD and NO-TPD. Also, its catalytic activity on CH_4-SCR denitrification reaction was evaluated with fixed-micro reactor. Results showed that Mn (10)/MOR catalysts have good activity and NO conversion rate reached to 30.93% when the temperature is 357°C. The activity of catalyst was influenced by the acidity and the ability of adsorption/desorption of NO.
