| 中文摘要 |
| 在以 γ- Al2O3小球作为填充物的介质阻挡放电条件下 ,研究放电电压 ( 9～ 16k V)、交流电源频率 ( 50～ 1600 Hz)、NO入口浓度 ( 50～1800 ml/m3)、气体空速 (1000～ 6500 h-1)、反应温度 ( 20～250℃ )、介质小球比表面积及加入 O2等因素对 NO分解率的影响 .发现提高放电电压、放电频率及介质小球比表面积能显著增加 NO分解率 ,O2 的加入对 NO的等离子体分解有强抑制作用 . |
| 英文摘要 |
| The non thermal plasma induced decomposition of NO in N2 in a dielectric barrier discharge reactor with γ Al2O3 pellet bed was investigated.The effects onto the NO decomposition of the following experimental factors were systematically examined:electrical discharge voltage(9～16kV),the frequency of the electric power supply(50～1600Hz),NO concentration in the reactant gas(50～1800ml/m3),gas space velocity(1000～6500h-1),reaction temperature(20～250℃)as well as the specific surface area of the γ Al2O3 and the addition of O2.It was found that raising the discharge voltage and the frequency of the electrical power supply as well as the specific surface area of γ Al2O3 pellets can enhance the NO decomposition efficiency.Addition of O2 into the reactant gas dramatically inhibits the NO decomposition. |
