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

Abstract

In order to study the NOx 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.
