| titleOfInvention | Preparation method of low-temperature denitration catalyst |
| abstract | The invention discloses a preparation method of a low-temperature denitration catalyst, which comprises the steps of dissolving a tungsten-containing precursor and citric acid in deionized water to obtain a mixed solution A, dissolving a manganese-containing precursor and an ionic liquid template in deionized water to obtain a mixed solution B, dropwise adding the mixed solution B into the solution A, standing for 2-4 h to obtain a mixed solution C, and slowly evaporating the mixed solution C to obtain a solution D with the relative density of 1.15-1.25; and (3) treating the solution D in a hydrothermal kettle at 220-250 ℃ for 48-72 h, naturally cooling to room temperature to obtain a product E, drying the product E at 110 ℃ for 12h to obtain a pre-product, placing the pre-product in a muffle furnace, raising the temperature to 300-400 ℃ at a heating rate of 1 ℃/min, and roasting for 5h to obtain the denitration catalyst. The product of the invention has MnWO 4 The novel denitration catalyst with the crystal structure has a high specific surface area, and can be 100-200% o High catalytic activity and SO resistance in the C range 2 Poisoning performance. |
