Abstract:
Characteristics of NO x removal combining dielectric barrier discharge (DBD) plasma with selective catalytic reduction (SCR) by C 3 H 6 were investigated under the conditions of high NO x concentration and high space velocity at various temperatures. Experiment results show that there were no obvious removal of NO x and NO in the only C 3 H 6 -SCR system and only DBD system individually. But the high NO x removal rate was achieved in C 3 H 6 -SCR cooperating with DBD plasma system. Especially NO x removal rate can reach up to 88.5% at 150 °C simulating diesel engine exhaust temperature. It can be seen that when discharge comes into being, the catalystic activity was enhanced with discharge strengthened, so that the NO x was almost completely removed. In the course of NO x removal, DBD played an important role in oxidizing NO to NO 2 and activating C 3 H 6 and catalysts to reduce NO x .
