The invention relates to the technical field of flue gas treatment, and discloses a desulfurization and denitrification agent, comprising the following raw materials in parts by weight: 10-15 parts of raw coal, 5-8 parts of dilute nitric acid, 8-13 parts, and 10-15 parts of ferric nitrate. share. The surface of the desulfurization and denitrification agent has the effect of adsorption and catalytic oxidation of SO 2. When there is no oxygen and water vapor in the flue gas, the activated coke adsorbs SO 2 only by physical adsorption, and the adsorption amount is small, and when there is oxygen in the flue gas. In the presence of water vapor, chemical adsorption occurs in addition to physical adsorption. The adsorbed SO 2 reacts with O 2 in the flue gas under the catalytic oxidation of activated coke to generate SO 3 , and then reacts with water vapor to generate sulfuric acid, making it The adsorption capacity is greatly increased. |
