Abstract

Effect of additives and catalysts has been investigated on NO_x (including N₂O) removal using discharge plasma. Additives such as H₂O, C₂H₄ are considered to be the source of OH and CH radicals. Though they are one of the important factors to enhance the NO_x removal chemical reactions, no systematic experiment has been carried out yet. It was confirmed that the hydrocarbon addition plays a dominant role in the NO _x removal efficiency compared to the water vapor addition. Effect of catalysts such as Ca(OH)₂ was investigated, and were found to enhance NO_x and N₂O removal efficiency
