A. Jaworek et al., REMOVAL OF NOX FROM NO2-NO-N-2 MIXTURE BY A PULSED AND DC STREAMER CORONA IN A NEEDLE-TO-PLACE REACTOR, Czechoslovak journal of Physics, 45(12), 1995, pp. 1049-1061
The results of laboratory experiments on reduction of NOx in the oxyge
n free gas mixture NO2:NO:N-2 simulating exhaust gas, by means of puls
ed and de streamer corona discharges generated in a needle-to-plate re
actor have been presented. The results show that the de corona dischar
ge is more efficient in De-NOx process than the pulsed corona discharg
e. This is in contrast to the results obtained in the wire-to-cylinder
reactors where the pulsed corona discharge removes NOx more efficient
ly. The results also lead to the conclusion that in the de streamer co
rona discharge the short pulses and long interelectrode distances are
recommended in order to increase the NOx conversion rate.
