| titleOfInvention | A kind of composite oxide catalyst for NH3-SCR denitrification and preparation method thereof |
| abstract | The invention discloses a composite oxide catalyst for NH 3 -SCR denitrification, which is characterized in that it is a metal composite oxide SnO x -WO x -BiO x composed of oxides of tin, tungsten and bismuth, wherein The molar ratio of tin and bismuth elements is 0.1-10.0, and the molar ratio of tin and tungsten elements is 0.1-10.0. The low-temperature reaction activity and stability of the catalyst are good, and it has a NOx conversion rate of 72%~100% and a N2 selectivity of more than 90% at 200~450°C. Using urea as a precipitating agent, the catalyst prepared by homogeneous co-precipitation can make the active components uniformly dispersed, which overcomes the shortcomings of conventional precipitating agents such as corrosion and uneven dispersion of active components. Post-treatment of the catalyst by hydrothermal treatment is conducive to the formation of a solid solution of the active components, giving full play to the synergistic catalytic effect among Sn, W, and Bi, and effectively improving the denitrification performance of the catalyst. |
