Oxidation of Nitrogen Monoxide by Corona Discharges -Effect of Discharge Conditions-

Abstract

Nitrogen monoxide NO was oxidized to nitrogen dioxide NO₂ with corona discharge in the presence of 02. Electrical factors were studied in the oxidation reaction. The following results were obtained:
( 1 ) Negative corona is most effective for the discharge oxidation of NO.
( 2 ) For a given applied power per unit gas volume W(Wh/m8), the amount of NO oxidation, q is independent of the residence time of the gas mixture, and proportional to W0.7-0.8.
( 3 ) At a constant power W the amount of NO oxidation increases with the decrease of the radius of the discharge pipe used R(mm).
( 4 ) The radius of discharge wire r(mm) has an optimum value rM, for the discharge reaction.
These results are summarized by
Where a and 8 are experimentally determined parameters; a=0.7-0.8, 80(rrm), O(rrm).
