| Summary: | A novel adsorption material of bimetallic Cu and Ni⁃doped TiO2⁃modified carbon nanotubes was prepared by sol⁃gel methodmethod,and experiments on simultaneous desulfurization and denitrification were carried out.The effects of O2 volume fraction,H2O volume fraction and volume airspeed on desulfurization and denitrification were studied,Under the condition of a molar ratio of Cu to Ni of 2.The results showed that the adsorption capacity of MWCNTs/Cu⁃Ni⁃TiO2 was significantly better than that of single⁃metal modified materials. Under the condition of simulating flue gas, the adsorption effect of the bimetallic modified material was the best when the mass concentration of SO2 was 3 140 mg/m3, the mass concentration of NO was 736 mg/m3, the volume fraction of water vapor was 5%, the fraction of O2 was 8%, and the volume space velocity was 2 598 h-1. The optimal adsorption amount of SO2 was 20.43 mg/g, and the optimal adsorption amount of NO was 0.86 mg/g. |
