【 摘 要 】

References(20)With more stringent environmental regulations or acts being implemented, the research on developing a desulfurization/denitrification technology with high efficiency and cost performance becomes very urgent. In this paper, TiO2 catalyst with the addition of different promoters and additives were tested in a laboratory scale plasma reactor. Promoters are V2O5 and K2O–V2O5, and additives are H2O and H2O2, respectively. The experimental results indicate that the promoters (V2O5 and K2O–V2O5) are considerably effective in promoting the activity of TiO2 catalyst in the presence of plasma, which causes the SO2 oxidation rate to increase. Meanwhile, K2O–V2O5 (K-promoter) is found to be a better promoter than V2O5. Except for promoters, the additives (H2O, H2O2) also have an important impact on SO2 oxidation in the case of simultaneously using plasma and TiO2 catalyst.
