Tsimbalyuk A. Kinetics of ethanol conversion in non-equilibrium plasma

The developed kinetic mechanisms model are used for studying the ethanol conversion in glow discharge at low and atmospheric pressure for the temperature of gas mixture in the range 290-1450 K. The main reactions leading to the generation of stable molecules such as H2, CO, CO2, CH4 etc are defined. In addition, the influence on the electron energy distribution function of the component content of gas mixture and its temperature is studied. The influence of experimental conditions such as gas temperature, initial component content of the mixture, electrical power etc on the compound of the mixture on the outlet of plasma chemical reactor is defined. The possibility of development of the ultraviolet lamp working on the hydroxyl radicals OH is analyzed. These radicals can be generated during the glow discharge on the mixture of ethanol and water vapors. The kinetic mechanism of generation and decay of OH is defined. The processes reducing the operation time of lamp are discussed. The ethanol conversion in the "tornado"-type plasma chemical reactor is studied by the numerical model. The working gas is the mixture of air with carbon dioxide, ethanol and water. The weak dependence on the rate of CO2 pumping of the main species concentrations is found. Also, it is found that the increase in the gas temperature results in the increase in the ratio between concentrations of H2 and CO. This indicates on the possibility of using the pyrolysis camera for the control of the component content of syn-gas. The efficiency of ethanol conversion in glow and barrier discharges is analyzed. It is shown that the use of glow discharge for the ethanol conversion is more efficient. In addition, the kinetics of plasma chemical reactions in barrier discharge is studied.
