CH4 reforming with CO2 in a nanosecond pulsed discharge. The importance of the pulse sequence

The plasma dry reforming reaction of methane with carbon dioxide is investigated in a nanosecond repetitively pulsed discharge, type that offers some the highest performance and non-equilibrium characteristics. experiment’s purpose was to examine effect varying sequence high-voltage pulses. We find when successive pulses are closer than 500 μs, memory-dominated regime gradually develops, which influences subsequent breakdown events. While reactant conversions increase energy, both energy efficiency by shortening inter-pulse time at same energy. This finding suggests power not only thing matters achieve better performance. How it delivered can make significant difference, particular for CO2, whose conversion doubles maximum molecule investigated, 1.6 eV molecule-1.
