Removal of NO by Selective Catalytic Reduction with Ethylene over Catalyst Cu/ZSM-5

Abstract:

Article Preview

The selective catalytic reduction of nitric oxide by ethylene was studied over Cu/ZSM-5 catalyst in the temperature range of 200-550°C, in which NO cannot be reduced by ethylene without Cu/ZSM-5 catalyst. Prepared Cu/ZSM-5 catalyst in varies loading as Na/ZSM-5 by the wet impregnation method, and the effect of the catalytic activity was studied in varies fitting temperatures. Several influencing factors, such as the different reaction temperatures, oxygen gas concentration, and Cu2+ concentration were investigated. Cu-Ce-ZSM-5 catalyst was prepared by wet impregnation method and the metallic influence of CeO2 to the catalytic ability was studied.
