| 摘 要： | 采用介质阻挡放电(DBD)等离子体技术降解强温室气体CF4，考察了外加气体氧气(O2)、空气、氩气 (Ar) 对DBD降解CF4的影响. 结果表明:随着放电时间的延长，CF4降解率升高. 3种外加气体条件下，CF4的降解率依次为Ar>空气>O2. 外施电压1 000 V，Ar条件下放电4 min，CF4降解率可达98.2%，而O2条件下CF4降解率只有36.9%. 水汽对CF4降解有一定抑制作用. 红外光谱检测结果表明，降解产物主要为CO2，CO和COF2.

| Abstract: | Carbon tetrafluoride(CF_4),a strong greenhouse gas,was destructed with dielectric barriers discharge(DBD).The experimental results indicated that the decomposition efficiency of CF_4 increased with the increase of discharging time.In addition,we investigated the influence of three kinds of additive gases(Ar,Air,O_2) on decomposition efficiency of CF_4,The results showed that decomposition efficiency can be increased to some extent,following the order: Ar > Air > O_2.Decomposition efficiency of CF_4 can reac... |
