采用催化剂增强了非热等离子体从室温到500/spl℃的高温NO/sub x/脱除反应。NO/ subx /去除率受催化剂类型和气体温度的影响较大。当传统的汽车用三路催化剂在500℃下活化时，非热等离子体对NO/ subx /的去除效果不明显。在合成烟气中加入碳氢化合物（乙烯）后，沸石催化剂在高温下变得非常活跃。在200/spl℃以下，证实了非热等离子体和催化剂的联合效应。采用沸石催化剂与烃类结合的方法，在500℃/spl℃温度下，无需非热等离子体放电，可脱除合成烟气中80%以上的NO/sub / x。非热等离子体处理在催化反应为主的高温条件下也能发挥作用。
Catalysts were used to enhance NO/sub x/ removal reactions by the nonthermal plasma from the room temperature to high temperature, 500/spl deg/C. NO/sub x/ removal rate was significantly affected by the type of the catalyst or the gas temperature. When the conventional 3 way catalyst for an automobile was activated at 500/spl deg/C, nonthermal plasma was not effective in removing NO/sub x/. When hydrocarbons (ethylene) were added to the synthetic flue gas, zeolite catalyst became very active at high temperature. Combination effect of nonthermal plasma and catalyst was confirmed below 200/spl deg/C. More than 80% NO/sub x/ was removed from synthetic flue gas by combination of zeolite catalyst and hydrocarbons without nonthermal plasma discharge at 500/spl deg/C. Nonthermal plasma treatment could be useful even at high temperature where catalytic reaction were dominant.
