EFFECT OF ANTIMONY DOPING ON DENITRATION PERFORMANCE OF Mn-Ce/TiO2 CATALYST |
| |
| Abstract: | A series of Sb doped Mn-Ce-Sb/TiO2 catalysts was prepared by impregnation method. The effect of Sb/TiO2 molar ratio on the denitration performance of the catalysts was investigated. The catalysts Mn-Ce/TiO2 and Mn-Ce-Sb/TiO2 (Sb/TiO2 molar ratio 2∶10) were characterized by XRD, BET, NH3-TPD and H2-TPR, and the denitration performance, sulfur resistance and water resistance of the two catalysts were compared. The results showed that Sb doping was beneficial to the dispersion of active components on the support, to the interaction between active components and support and the low temperature redox reaction. In addition, Mn-Ce-Sb/TiO2 (2∶10) catalyst has larger specific surface area, more surface acidic sites and excellent redox performance. Therefore, compared with Mn-Ce/TiO2 catalyst, Mn-Ce-Sb/TiO2 (2∶10) catalyst has better SCR activity of NOX, better resistance to sulfur and water. |
