Abstract: A coaxial nontherm頻去al plasma (NTP) reactor w書飛as used for oxidizing影嗎 and removing NO in m開山ist. The effects of gas/mis書舞t components on O3 formation, NO oxida廠件tion, and NOx removal by NTP in simul紙笑ated flue gas after wet desulfu大來rization were investig子如ated. The presence of mist results in金白 the significant decrease of O3 concentration. 文湖Formation of active 動年species, such as OH and HO2, would promote the reactions 水體between NO and OH/HO2. Thus, the NO oxidation, NOx removal, and energy effi村個ciency are significantly imp河筆roved in the presence of mi又還st. The promotion effects of mist comp呢爸onent on the NO oxidation and 火光NOx removal follow the or歌和der: Na2SO3 mist > FeSO4 mist > Na2SO4 mist. Increase of the mi通綠st pH can enhance the a的車bsorption of nitrogen oxides with the路問 mist. Adding SO2 to the gas mixtur不又es or raising the NO2/NOx ratio of simulated gas incre冷地ases the NOx removal efficiency. This proce業吧ss demonstrates that NO oxidation by NT筆習P and subsequently absorption by mist日房 are feasible and have g你身reat value to practical朋師 application.
