Abstract: A coaxial nonthermal 下能plasma (NTP) reactor was us來子ed for oxidizing and removing NO i也熱n mist. The effects of gas/mist compon物車ents on O3 formation, NO oxidation, and NOx removal by NTP in si地訊mulated flue gas after wet desulfuri拍們zation were investigated. The pr明草esence of mist results in the signifi行有cant decrease of O3 concentration. Fo城海rmation of active speci黃是es, such as OH and HO2, would promote the reactions b子費etween NO and OH/HO2. Thus, the NO oxidatio開爸n, NOx removal, and energy eff街在iciency are signific舞森antly improved in the著快 presence of mist. The promotion effect山話s of mist component on the NO oxidati看影on and NOx removal follow the 笑西order: Na2SO3 mist > FeSO4 mist > Na2SO4 mist. Increase of the mist pH c筆我an enhance the absorption of nit靜生rogen oxides with the mist. A謝會dding SO2 to the gas mixtures or rai喝林sing the NO2/NOx ratio of simulated gas 司區increases the NOx removal efficiency. Th森錯is process demonstrates that NO舊家 oxidation by NTP and 什謝subsequently absorption by mist a也在re feasible and have great v農線alue to practical application.
