“…[21][22][23] In particular, the fast response of plasma reforming enables it to utilize the fluctuant renewable electricity and convert the electric energy to chemical energy through the endothermic reforming process with high energy efficiency. [24,25] Steam reforming of ethanol and methane for hydrogen production has been reported using various nonthermal plasmas, such as dielectric barrier discharge (DBD), [26][27][28] corona discharge, [29][30][31] microwave discharge, [32][33][34] and gliding arc discharge. [35][36][37] In terms of the hydrogen production rate and energy efficiency, it was found that warm plasmas (e.g., gliding arc and microwave) are better than cold plasmas (e.g., DBD and corona) at a comparable range of reactant conversion.…”

Toward hydrogen production from renewable sources, coreforming of dilute bioethanol (5 mol% ethanol) and methane using gliding arc discharge warm plasma is reported. For warm plasma alone, increases in methane to ethanol ratio and specific energy input lead to improving hydrogen yield, but low energy efficiency (<60%). The warm plasma coupled with Ni/CeO2/Al2O3 catalyst in a heat‐insulation reactor achieves an energy efficiency of 80%, but the large axial‐temperature drop of the catalyst bed causes low conversions. Therefore, additional heating is provided to maintain the catalyst bed temperature. Under optimal conditions, total carbon conversion of 97% and hydrogen yield of 78% are achieved with an energy cost of 1.16 kWh/Nm3 and energy efficiency of 85%.

The paper represents the results of the experimental study of steam methane reforming under the action of spark discharge on water surface. Values of conversion rate and output of reaction products at methane pressures of 1 to 5 atm were obtained, and specific energy consumption of reforming process was determined. Pulse generator with a voltage amplitude up to 200 kV and a pulse duration of 15 ns was used to power the discharge. Although an increase in pressure decreases both the methane conversion rate and the energy deposition into the gas mixture, the conversion efficiency and specific energy consumption remain the same. The obtained minimum value of specific energy consumption for steam methane reforming amounted to 10 eV/molecule.
