Thermal Stimulation as a Prevailing Mechanism of Methane Conversion in Barrier Discharge

Аннотация

The effect of energy deposition on the composition of the outlet mixture was studied in a plasmachemical reactor with barrier discharge. The composition of the conversion products was analyzed using a gas chromatograph and a quadrupole mass spectrometer. The process mainly occurred by the thermal mechanism of chain initiation and propagation. At an energy input of 3.25 eV/molecule, the selectivity for the main reaction products was 11.56% for acetylene, 14.76% for ethylene, 30.51% for ethane, 16.84% for propylene, 15.01% for propane, and 7.02% for hydrogen.
