Kurzfassung:
By using self-designed non-thermal plasma reactor, the influences of discharge power, initial concentration of C 3 H 6 and O 2 concentration on NO pro-oxidation in C 3 H 6 /NO/N 2 /O 2 mixture were studied. The obtained results indicate that with the increasing of discharge power, NO 2 /NO x ratio grows firstly and then decreases after reaching a peak value, while NO x conversion efficiency and N 2 O concentration gradually rise. Increasing initial concentration of C 3 H 6 or O 2 concentration would help to enhance NO oxidation efficiency. With the same discharge power, NO x conversion efficiency grows with the increasing of C 3 H 6 initial concentration while reduces with the increasing of O 2 concentration. Controlling the concentration of C 3 H 6 and O 2 in exhaust gas can lead the NO 2 /NO x ratio to reach 50%, which is benefit to NO x conversion with SCR system.
