Abstract
An electric discharge plasma reactor combined with a catalytic reactor was studied for removing nitrogen oxides. To understand the combined process thoroughly, discharge plasma and catalytic process were separately studied first, and then the two processes were combined for the study. The plasma reactor was able to oxidize NO to $NO_2$ well although the oxidation rate decreased with temperature. The plasma reactor alone did not reduce the $NO_x (NO+NO_2)$ level effectively, but the increase in the ratio of $NO_2$ to NO as a result of plasma discharge led to the enhancement of $NO_x$ removal efficiency even at lower temperatures over the catalyst surface $(V_2O_5-WO_3/TiO_2)$. At a gas temperature of 100°C, the $NO_x$ removal efficiency obtained by using the combined plasma catalytic process was 88% for an energy input of 36 eV/molecule or 30 J/l.
