Abstract
Effect of additives and catalysts has been investigated on NO/sub x/ (including N/sub 2/O) removal using discharge plasma. Additives such as H/sub 2/O, C/sub 2/H/sub 4/ are considered to be the source of OH and CH radicals. Though they are one of the important factors to enhance the NO/sub 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/sub x/ removal efficiency compared to the water vapor addition. Effect of catalysts such as Ca(OH)/sub 2/ was investigated, and were found to enhance NO/sub x/ and N/sub 2/O removal efficiency.
