摘要
Abstract
Adsorption removal experiments of SO2 and NO in simulated industrial flue gas were carried out with polyacrylonitrile-base activated carbon fiber （PAN-ACF） above the dew-point temperature. Desulfurization efficiency and denitrification efficiency of ACF were studied separately by means of varying ACF loading capacity in fixed-bed reactor, reaction temperature, vapor and 02 volume fraction in flue gas. Meanwhile, the effect of the inlet SO2 or NO concentration on the removal efficiencies of simultaneous desulfurization and denitrification was also studied. The results show that PAN-ACF possesses good desulfurization performance and certain denitri- fication performance. The desulfurization efficiency and denitrification efficiency of ACF increase with increasing of ACF loading capacity and 02 volume fraction, the efficiencies decrease with incresing of reaction temperature, and the efficiencies increase firstly and then decrease with increasing of vapor volume fraction. For simultaneous desulfurization and denitrification, SO2 shows an obvious inhibiting effect on the removal of NOx, while NO has little effect on the removal of SO2.关键词
