A threefold increase in the CO2 conversion and energy efficiency due to thecooling of the post-discharge region by the counter gas flow has been achievedin the plasma of an atmospheric pressure discharge supported by microwaveradiation of a gyrotron with a frequency of 24 GHz in a carbon dioxide gasflow. The role of convective heat transfer in the process of gas mixturecooling in the post-discharge region has been experimentally demonstrated. Atnitrogen quench gas flow of 4.5 l/min, the CO2 conversion was 23.8 % and energyefficiency was 19.7 %. The possibility of using the flow of cooled gas mixture(CO2,CO,O2) taken from the reactor as quenching gas has been experimentallydemonstrated, which made it possible to achieve a CO2 conversion degree of 23.4% and to eliminate the problem of dilution of reaction products by third-partygases. Based on numerical modeling, it is shown that the increase in theconversion degree upon the destruction of the plasma torch structure is due tothe increase in heat exchange with the surrounding atmosphere, and theefficiency of this destruction is determined by the velocity and density ofquenching gas.
