Abstract
In order to understand the reaction mechanisms of NO removal in Dielectric Barrier Discharge reactor, the effect of gas composition on plasma reduction of NO was studied. In this experiment, single-layer barrier tube plasma reactor was used to study the influence of O2and C2H4(ethylene) to NO removal rate. The result indicated that: with the increase of input power, NO removal efficiency increased gradually in the N2/NO system; The O2added to the gas caused removal efficiency to reduce. There was no significant effect on removal of NO with C2H4added alone. In the N2/NO/O2/C2H4gas condition, C2H4will promote the conversion from NO to NO2, the removal efficiency of NO increased as more C2H4was added. And the presence of C2H4was conductive to reduce input power.
