What is Application of Surfactant-modified Cordierite-based Catalysts in Denitration Process about?

The Mn-based oxides and Cu-based oxides were used as active components. They were supported on the honeycomb ceramic cordierite carrier and the carrier was modified by the surfactant TEP (Double palm carboxyethyl-hydroxyethylmethyl sulfateammonium salt). By changing the interventional position of the surfactant, it was contrasted the influence of the presence or the absence of TEP on the dispersibility of the metal oxides and the denitration performance of the catalyst. It was characterized the catalyst activity by XPS, TPR, SEM and FITR. The reaction activation energy was calculated by reaction kinetics to further clarify the denitration mechanism of the catalyst. The results indicated that TEP could increase the impregnation of the catalyst and make the dispersion of metal oxide more uniform. And the denitration efficiency of MnO X /TEP + CuO X + TEP (M T CT) catalyst was higher than others. According to the surface reaction Arrhenius equation, the activation energy of M T CT catalyst was 85.39 kJ/mol while that of MnO X -CuO X (MC) catalyst was 118.71 kJ/mol. The M T CT catalyst
