Effect of Coexisting Gases on NO Removal Using Corona Discharge SAITO, Masahiro KOGA, Hironobu YOSHINAGA, Setsuri ARAI, Masataka 本文データは学協会の許諾に基づきCiNiiから複製したものである NO Removal Corona Discharge DeNOx Ozone Coexisting Gas application/pdf Journal Article Effects of H_2O, CO_2, CH_4 and C_2H_4 contained in automotive exhaust gas on NO removal by using a DC corona discharge were investigated experimentally. In this experiment, N_2/O_2/NO mixture was used as a base gas of the simulated exhaust gas. To clarify the effect of the individual coexisting gas on NO removal, each coexisting gas was added to the base gas. The results showed that the existence of H_2O or C_2H_4 was effective for NO removal with low energy density. Also, when negative corona discharge was applied to the simulated exhaust gas (N_2/O_2/NO/H_2O/CO_2/C_2H_4 mixture), the efficiency of DeNOx was more than 90%. However, the by-products such as CO, O_3, HNO_3 and N_2O increased with increasing the energy density. It was found that the optimum energy density of corona discharge was about 250J/L for DeNO_x of simulated exhaust gas. 社団法人日本機械学会 2006-11-15 2017-03-27 eng journal article VoR http://hdl.handle.net/10087/5694 https://gunma-u.repo.nii.ac.jp/records/3030 13408054 AA10888815 JSME international journal.
