文摘

NO catalytic oxidation performances have been investigated on a Mn鈥揅o鈥揅e鈥揙x catalyst by using nonthermal plasma (NTP) reactor: the 鈥淧RFC鈥?reactor. In the PRFC system, the plasma reactor was followed by the catalyst. The results showed that the NO catalytic oxidation of the Mn鈥揅o鈥揅e鈥揙x catalyst was significantly enhanced by the nonthermal plasma in the PRFC system at the temperature range of 50鈥?50 掳C. The oxidation capability of the catalyst was improved with the increase of the input energy density in the PRFC system. It was also found that the activity was suppressed when SO₂ was present in the reaction mixture, whereas the catalytic oxidation ability was obviously enhanced under the NTP-assist, because NTP system is conducive to synchronous SO₂ removal. The antipoisoning performance and NO catalytic oxidation capacity of this mechanism are superior to those of others reported in the literature.
