Abstract: A coaxial nonthermal plasma (大可NTP) reactor was used for oxidizi費相ng and removing NO in m很短ist. The effects of gas/mist c木錯omponents on O3 formation, NO oxida通司tion, and NOx removal by NTP會雪 in simulated flue gas a光裡fter wet desulfurization wer哥雨e investigated. The presence of 拿愛mist results in the signific體見ant decrease of O3 concentration. Formation of acti煙兵ve species, such as OH and HO2, would promote the reactions be朋光tween NO and OH/HO2. Thus, the NO oxidation, NOx removal, and energy eff靜見iciency are significantly improv鄉車ed in the presence of mist. The 歌家promotion effects of mist component 在山on the NO oxidation and NOx removal follow 術媽the order: Na2SO3 mist > FeSO4 mist > Na2SO4 mist. Increase 花你of the mist pH can enhance the abso慢飛rption of nitrogen oxid劇爸es with the mist. Adding SO2 to the gas mixture事這s or raising the NO2/NOx ratio of simulated gas in票音creases the NOx removal efficiency村區. This process demonstrates that NO o說線xidation by NTP and subse民公quently absorption by 影林mist are feasible and鄉站 have great value to practical冷我 application.
