Abstract: The corona discharge is widely used to promote chemical reactions leading to reduction of NOx and production ofdifferent products depending on various parameters of the discharge and composition of the initial gas mixture. Among variouschemical additives the influence of CO2 has been studied only partially. Therefore, laboratory experiments were carried out toinvestigate and describe the changes in mixtures containing NOx, CO2, N2, O2 in the presence of H2O (ultrasonic humidifier wasused for this purpose) or without while using positive DC corona discharge. The products of the process were analyzed by infraredspectrometry. Besides the concentration changes of the main gas components of the gas mixture, the products as ozone, amides,amines, imides and other compounds or functional group were detected in the spectra.
