Abstract: A coaxial nonthermal plasma 年這(NTP) reactor was used for oxidiz人來ing and removing NO in mist. The ef司弟fects of gas/mist components on O3 formation, NO oxid時能ation, and NOx removal by NTP in simula務短ted flue gas after wet de公坐sulfurization were investigate銀坐d. The presence of mist re工個sults in the significan草房t decrease of O3 concentration. Formation of activ店子e species, such as OH 我我and HO2, would promote the rea體生ctions between NO and OH/H鐵草O2. Thus, the NO oxidation, NOx removal, and energ媽化y efficiency are significantly imp大從roved in the presence of mist. The pro近在motion effects of mist component on 吧醫the NO oxidation and NOx removal follow the order: Na2SO3 mist > FeSO4 mist > Na2SO4 mist. Increase of the mis畫雪t pH can enhance the absorption of 花生nitrogen oxides with the mist. Adding什門 SO2 to the gas mixtures o雨為r raising the NO2/NOx ratio of simulate舞業d gas increases the N少呢Ox removal efficiency. This 討近process demonstrates that冷文 NO oxidation by NTP and subsequent裡也ly absorption by mist a國厭re feasible and have great value to pr畫唱actical application.
