Abstract

Abstract

With the increasing environmental problems, the removal of nitrogen oxides (NO_x) in flue gas has become an urgent problem. In this paper, the cordierite honeycomb-supported denitration catalyst was prepared by simultaneous impregnation method. The effects of vanadium content, temperature, gas hourly space velocity and acid treatment on the denitration efficiency of cordierite-supported denitration catalyst were studied. At the same time, the catalyst was subjected to physical and chemical characterization by means including BET and XRD. The results showed that the supported denitration catalyst could achieve good denitration effect, the denitration efficiency gradually increased with the increase of V₂O₅ content, as the temperature rose, the efficiency increased first and then decreased; at 340℃, the supported catalyst achieved the best denitration effect, the denitration efficiency was above 98% (the gas hourly space velocity was 18000 h^-1); the de-NO_x efficiency of sulfuric acid treated catalyst increased by 1~3 percents, while that of hydrochloric acid treated catalyst decreased by 4~8 percents; the loading rate of the supported catalyst was maintained at about 25%, and the shedding rate after ultrasonic treatment was less than 10%.
