The authors carry out a model calculation of the kinetics of the decomposition of carbon dioxide in the presence of sulfur in a moderate-pressure nonequilibrium discharge. The process is stimulated by the vibrational excitation of CO/sub 2/. Kinetic curves and the time variation of the vibrational and translational temperatures are calculated. The dependence of the energy efficiency on the specific energy input has been obtained. The optimal energy input is 4 J/cm/sup 3/. The minimal energy comsumption per CO molecule is 2.7-3.5 eV. The results of the calculations are consistent with the experimental results in the case of a nonequilibrium UHF discharge. The mechanism of the process, which accounts for the results, particularly the higher efficiency of the process in comparison to the dissociation of pure CO/sub 2/, has been ascertained.
