摘要：
Recent results on the efficiency of CO2 conversion in discharges in CO2-N-2 mixtures are discussed. Conditions are considered when the dominating conversion mechanism is dissociation of CO2 molecules in collisions with nitrogen molecules in several electronically excited states. Its efficiency is determined by the values of dissociation yields in these collisions. Knowledge of dissociation yields for various N-2 excited states is rather poor. In this paper, the effects of variation of these yields on the conversion efficiency are evaluated. Comparison of the obtained estimates with available experimental data allows ascertaining the yield values.
