Large quantities of Carbon Oxides (CO x ) Sulfide Oxides (SO x ) and Nitride Oxides (NO x ) are the main cause for acid rains, photochemical smog and Greenhouse effect. The plasma process within induced free energetic electrons discharge is one of the most effective methods of reducing SO x , NO x and CO 2 from industrial flue gases. This paper for dissociation of a atmosphere pollutant gases by corona discharge. The reactor consists of two coaxial, specially designed cylindrical electrodes. An ac barrier corona discharge at atmospheric pressure is generated by application of high voltage to the inner electrode while the outer electrode is grounded. Discharge by products of air and NO x are measured by a mass spectrometer in order to investigate the effect of a surface multidipole magnetic fields on the corona discharge and on the pollutant gas reduction.
