Title
Modelling the dynamics of hydrogen synthesis from methane in nanosecond-pulsed plasmas
Author
Abstract
A chemical kinetics model was developed to characterise the gas-phase dynamics of H-2 production in nanosecond-pulsed CH4 plasmas. Pulsed behaviour was observed in the calculated electric field, electron temperature and species densities at all pressures. The model agrees reasonably with experimental results, showing CH4 conversion at 30% and C2H2 and H-2 as major products. The underlying mechanisms in CH4 dissociation and H-2 formation were analysed, highlighting the large contribution of vibrationally excited CH4 and H-2 to coupling energy from the plasma into gas-phase heating, and revealing that H-2 synthesis is not affected by applied pressure, with selectivity remaining unchanged at similar to 42% in the 1-5 bar range.
