Abstract: A coaxial 學計nonthermal plasma (NTP讀器) reactor was used for oxidizing an會河d removing NO in mist. The effect數下s of gas/mist components on O3 formation, NO 的紙oxidation, and NOx removal by NTP in s得草imulated flue gas after wet desulfur司市ization were investigated.志分 The presence of mist resul我匠ts in the significant路她 decrease of O3 concentration. Formation of 家她active species, such as OH制來 and HO2, would promote the 女可reactions between NO and OH/HO為雜2. Thus, the NO oxida我頻tion, NOx removal, and energy 生歌efficiency are significantly i山白mproved in the presence of男暗 mist. The promotion effe見林cts of mist component on 門業the NO oxidation and NOx removal follow the ord文鐵er: Na2SO3 mist > FeSO4 mist > Na2SO4 mist. Increase of the mist pH 用子can enhance the absorption of ni厭師trogen oxides with the mist. Adding S服從O2 to the gas mixtures or raising t身光he NO2/NOx ratio of simulated gas increases海小 the NOx removal efficiency. This process 嗎弟demonstrates that NO 得歌oxidation by NTP and subsequently abs器子orption by mist are feasibl身錢e and have great value to pract嗎就ical application.
