Research on the Effect of C3H6 on NO Conversion Rate in a NTP Reactor

In order to study the NO_x plasma chemistry reaction mechanisms in NO/N₂/C₃H₆ and NO/N₂/O₂/C₃H₆ mixture gases, a coaxial tubular plasma reactor based on dielectric barrier discharge was designed, the effects of the C₃H₆ initial concentration on NO oxidation and reduction reactions were observed. The results showed that NO reduction reaction was very low and energy consumption was very high in NO/N₂ mixture gases, however, when C₃H₆ was added, NO conversion rate significantly increased. In NO/N₂/O₂ mixture gases, NO oxidation and reduction reactions simultaneously occurred and the oxidation of NO to NO₂ was the main reactions, when C₃H₆ was added to the mixture gases, NO conversion rate significantly increased and the energy consumption largely reduced.
