Abstract

The surface of activated carbon fibers was modified by discharge plasma. The adsorption and catalysis of SO2 and NO on activated carbon fibers were enhanced by changing the chemical functional groups of activated carbon fibers. The trend of SO2 adsorption per unit time of activated carbon fibers before and after modification was discussed. During the modification process, the specific surface area and the pore volume of the activated carbon fiber are significantly increased, which helps to improve the adsorption performance of the activated carbon fiber. Under the action of physical adsorption and chemical adsorption, the modified activated carbon fiber has improved the effect of desulfurization and denitrification. The test results show that 8kV is the best modified voltage. After modification, the desulfurization and denitrification effect is obviously improved. The SO2 removal rate is increased from 90% to 95%, and the NO removal rate is increased from 35% to 60%.
