Abstract: Positive DC corona discharge in a hemicylindrical discharge reactor was applied to mixtures containing N2, NO, O2, CO2 and H2O, while an NOx chemiluminescence analyzer and an IR spectrometer were used to evaluate the concentration changes and analyze the products of the process in the discharge chamber. The removal efficiency of 89% for NO and the energy cost of350 eV/molecule were achieved. Special attention was paid to the influence of CO2 on discharge, its character, performance and products of the process. In addition to the main components of the gas mixture (NO,NO2, CO2, CO etc.), othercompounds and functional groups (e.g., amides I–III, imides, NCO) have been identified among the products of theprocess.
