Calculated values of effective CH4, CO2 and H2O conversion, methanol (CH3OH) selectivity and yield, and thermal efficiency for plasma-based multi-reforming conditions, varying the concentration of the diluting agent N2, for a modelled DBD operating at an SEI of 3 kJ/L, with a fixed 1:1 mixture of CH4 and CO2.
