| titleOfInvention | Preparation method and application of hydrotalcite-based CoMnFe composite metal oxide denitration catalyst |
| abstract | The invention discloses a preparation method and application of a hydrotalcite-based CoMnFe composite metal oxide denitration catalyst, and belongs to the field of pollution control and treatment. The method comprises the steps of preparing a solution, titrating coprecipitation, carrying out hydrothermal treatment, carrying out suction filtration, washing and drying by using cobalt nitrate hexahydrate, ferric nitrate nonahydrate and manganese nitrate as raw materials, sodium hydroxide as a precipitator, sodium citrate as a complexing agent and deionized water as a solvent and a detergent to prepare a CoMnFe hydrotalcite-like compound (CoMnFe-LDHs) precursor; and roasting the CoMnFe-LDHs at a certain temperature to obtain the CoMnFe composite metal oxide (CoMnFe-LDO) denitration catalyst. The obtained composite oxide is applied to the selective catalytic reduction reaction (NH) of ammonia gas 3 -SCR) exhibits excellent denitration activity (120-270 ℃, NO) x The conversion rate of the catalyst is more than 90 percent), and the N is high 2 Selectivity and good water-resistant and sulfur-resistant performance. |
