Synergetic Effect of Electric Discharges on Catalytic Methanol Decomposition for High-Efficiency Hydrogen Production

摘要

This paper describes the synergetic effect of electric discharges on catalytic methanol decomposition for high-efficiency hydrogen production. Inter-electrode material, void fraction in plasma region, and relative location of plasma to catalyst were selected as parameters to reveal the synergetic effect. Basically, the methanol conversion was increased when electric discharge was present on the catalyst. Copper-zinc catalyst showed the maximum conversion of 95.95% under the plasma. The increasing tendency in methanol conversion was different according to inter-electrode material and relative location of plasma to catalyst. The increase of methanol conversion only occurred when the plasma was overlaid on the catalyst. The hydrocarbons and carbon monoxide were detected under the plasma, originally which were not generated when the catalyst was used only.
