Abstract: The positive DC corona discharge in the hemi cylindrical discharge reactor was applied to mixtures containingN2, NO, O2 CO2 and H2O while NOx chemiluminescence analyzer and infrared spectrometry was used to analyze theproducts of the process in the discharge chamber. The removal efficiency of 80% for NO, and the energy costs 256eV/molecule was achieved. The attention was paid to the influence of CO2 on discharge, its character, performanceand products of the process. Besides the main components of the mixtures (NO, NO2, CO2 etc.) also othercompounds and functional groups (e.g. amides I-III, amines, imides, NCO) had been identified in the spectra
