Study of the Performance on Magnesia Base Catalyst Used for Flue Gas Denitration

To control contamination of flue gas emission NOx, the auther mixed method of preparing new magnesia base catalyst and researched on denitrificating flue gas by directness catalytic decomposition. Usually removal rate of NO is regarded on the main evaluation criteria. The author analysed calcination temperature of catalyzer manufacturing process, the temperature of flue gas desorption tower, bed height and efficiency denitrification of NO concentration. And discussed the result of both denitrate fore-and-aft of FT-IR and XRD. The experiment indicate that magnesia base catalyst is available to directness catalytic decomposition denitrificate flue gas. Through denitrification rate is from 85% to 95%.The ingredient of magnesia base catalyst is made from magnesia, firming agent, addition agent. Height denitration bed was 4-5 cm, denitration reaction temperature is 130-170degC. Through the analyses above , presumed that magnesia base catalyst exist activating of vice, and analyzed this vice preliminarily.
