Preparation method and application of rare earth-based high-temperature SCR denitration catalyst in CeO 2 ‑WO 3 ‑TiO 2 On the basis of the catalyst, the silica sol, the La oxide and the Cu oxide are introduced to modify the catalyst together, so that the synergistic effect of the silica sol and the oxides of the La oxide, the Cu oxide and the Ce oxide is found, the activity of the catalyst at high temperature is improved, and the application temperature range of the catalyst is widened. By introducing viscosity instead of part of TiO 2 Further improving the activity of the catalyst at the high-temperature section and widening the upper limit temperature of the activity window of the catalyst. |
