摘　　要：采用电容耦合等离子体和催化剂协同作用对干空气中的甲烷进行了氧化实验,并和没有放置催化剂时进行了对比,结果表明,放置催化剂后甲烷的分解效率明显提高,反应产物中CO2的选择性增加,副产物NO和NO2的浓度减少,反应所需的能耗降低。甲烷的最终氧化产物为CO、CO2和H2O。The synergistic effect of capacitively coupled plasma and catalyst for oxidation of CH4 in dry air was studied and compared to the cases without catalyst in the reactor. The result indicates that when the catalyst was presents, the CH4 removal efficiency was improved, the CO2 selectivity was increased in the reaction prod- ucts, the by-product concentration of NO and NO2 was decreased, and the energy consumption of reaction was reduced. The final products of CH4 oxidation were CO, CO2 and H2O.
