Abstract: A coaxial nonthermal pla鐘短sma (NTP) reactor was used for o費見xidizing and removing NO in 這飛mist. The effects of gas/mi商花st components on O3 formation, NO oxidation, an愛媽d NOx removal by NTP in simu人房lated flue gas after wet desulf妹森urization were investigated. The presen林請ce of mist results in t雨書he significant decreas員海e of O3 concentration. Formation of 什好active species, such as OH a又不nd HO2, would promote the reactions be遠吧tween NO and OH/HO2. Thus, the NO oxidation, NOx removal, and energ說房y efficiency are significantly im地內proved in the presence of 西讀mist. The promotion ef子電fects of mist component on the NO 鐘玩oxidation and NOx removal follow the order: Na微問2SO3 mist > FeSO4 mist > Na2SO4 mist. Increase of the mist pH can匠長 enhance the absorption of nitrog文一en oxides with the mist. Adding SO2 to the gas mixt鐘吃ures or raising the NO2/NOx ratio of simula雨章ted gas increases the NOx removal efficiency. Thi事謝s process demonstrate問技s that NO oxidation by N又那TP and subsequently abso都路rption by mist are feasible 從東and have great value to pract廠謝ical application.
