| titleOfInvention | Cerium/molecular sieve catalyst used for selective catalytic reduction of nitrogen oxides and preparation method thereof |
| abstract | The invention discloses a cerium/molecular sieve catalyst used for selective catalytic reduction of nitrogen oxides and a preparation method thereof. The invention overcomes the technical problems of a narrow operating temperature window, poor selectivity at a high temperature and potential harm to the ecological environment and human health of a vanadium-based catalyst system. The catalyst provided by the invention comprises a cerium oxide nanoparticle and a molecular sieve, wherein the molecular formula of the cerium oxide nanoparticle is CeO2, the molecular sieve is MCM56 (n(SiO2)/n(Al2O3)=15-30), and the mass ratio of the cerium oxide nanoparticle to the molecular sieve is 1:19 to 3:1. The invention also provides a preparation method for the catalyst. The preparation method comprises the following steps: synthesizing the cerium oxide nanoparticle by using a hydro-thermal synthesis method; and loading the cerium oxide nanoparticle on the molecular sieve MCM56 for removal of nitrogen oxides through NH3-SCR. The supported catalyst prepared by using the method has the advantages of uniformly dispersed active components, high activity, a wide temperature range and good stability. |
