Effect of the Volumetric Flow Rate of Reaction Mixture Components on Nonoxidative Reforming of Methane with Admixed Water in Dielectric-Barrier Discharge

详细

The effect of the volumetric flow rate of reaction mixture components on the nonoxidative reforming of methane with admixed water in dielectric-barrier discharge has been studied. An increase in the volumetric flow rate of water from 1.3 to 6 cm³/h did not exert a noticeable effect on the conversion of methane and on the concentrations of hydrogen and ethane in gaseous reaction products. An increase in the concentration of propane and butanes was observed, whereas the total ethylene and propylene content of the products decreased. An increase in the volumetric flow rate of methane from 5 to 60 cm³/min led to a decrease in the conversion of methane from 29.3 to 6.2 vol % and a decrease in energy consumption for its reforming from 88.3 to 34.7 eV/molecule, and it was also accompanied by a decrease in the rate of formation of gaseous alkanes and olefins. The experimental data confirmed previous conclusions on the reaction mechanism and kinetics of the nonoxidative reforming of methane in dielectric-barrier discharge, which were made using a mathematical model.
