Figure 2. The Effect of Ozone Induction on SO<sub>2</sub> and NO<sub>2</sub> Elimination

Caption

Ozone generated in an atmospheric-pressure non-equilibrium plasma was passed through the MnO2 filter together with simulated exhaust gas. The simulated exhaust gas consisted of 500 ppm SO2, 500 ppm NO2,10wt% O2, 6wt% CO2, an N2 base, and 50 ppm O3 (when plasma is induced). The MnO2 was supported on an alumina honeycomb filter and the flow conditions (space velocity of 104 h?1) mimicked typical vehicle exhaust streams and filter dimensions.
