可坐 Abstract: A coaxial nont綠我hermal plasma (NTP) r很舞eactor was used for ox習山idizing and removing NO in mist. T件黃he effects of gas/mist components on O友河3 formation, NO oxidation, 算老and NOx removal by NTP in simula習森ted flue gas after we理船t desulfurization were inve哥兵stigated. The presence of mist re離服sults in the significant decrease of O開南3 concentration.熱章 Formation of active spe內鐵cies, such as OH and HO2, would promote the reactions between 空資NO and OH/HO2. Thus, the NO oxidat少人ion, NOx removal, and energy efficien睡動cy are significantly improved in the pr訊他esence of mist. The promotion effe器請cts of mist component月但 on the NO oxidation and NOx removal follow the器裡 order: Na2SO3 mist > FeSO4 mist > Na2SO4 mist. Increase of the mis藍刀t pH can enhance the abso學鐵rption of nitrogen oxide村雪s with the mist. Add子問ing SO2 to the gas mix東鄉tures or raising the NO制可2/NOx ratio of simulated gas 南地increases the NOx removal efficiency. Thi市河s process demonstrates that NO oxidat小如ion by NTP and subsequ短美ently absorption by mist are feasib村可le and have great value to practica麗雜l application.
