Embodiment 1
[0017] Example 1: The CO content in the boiler flue gas of a coal-fired power plant is about 100mg / m 3 , SO 2 Content 2000mg / m 3 , NO X Content 300mg / m 3 , CO 2 Content 15% (mass percentage). The catalysts loaded in the CO removal tower, desulfurization tower, and denitrification tower are all semi-coke catalysts in Example 1 described in the patent (publication number CN 101362101A), and the semi-coke particle size is 4-10 mesh. Pass the flue gas into the CO removal tower with a space velocity of 1000h -1 , the reaction temperature is 160°C, so that a small amount of CO and NO react under the catalysis of activated semi-coke to generate CO 2 and N 2 ; The flue gas discharged from the CO removal tower enters the desulfurization tower again, and at a reaction temperature of 80°C, the O contained in the flue gas is utilized 2 SO in flue gas 2 Oxidation to SO 3 , and adsorbed on the catalyst; the flue gas after passing through the desulfurization tower enters the denit...
Embodiment 2
[0020] Example 2: The CO content in the boiler flue gas of a coal-fired power plant is about 80 mg / m 3 , SO 2 Content 2500mg / m 3 , NO X Content 500mg / m 3 , CO 2Content 15% (mass percentage). The catalysts loaded in the CO removal tower, desulfurization tower, and denitrification tower are all semi-coke catalysts in Example 1 described in the patent (publication number CN 101362101A), and the semi-coke particle size is 4-10 mesh. Pass the flue gas into the CO removal tower with a space velocity of 1200h -1 , the reaction temperature is 150°C, so that a small amount of CO and NO react under the catalysis of activated semi-coke to generate CO 2 and N 2 ; The flue gas discharged from the CO removal tower enters the desulfurization tower again, and at a reaction temperature of 90°C, the O contained in the flue gas is utilized 2 SO in flue gas 2 Oxidation to SO 3 , and adsorbed on the catalyst; the flue gas after passing through the desulfurization tower enters the denit...
