Heating effect of plasma catalytic reaction on the CH₄ reforming of CO₂ over Ni/γ-Al₂O₃ catalyst in dielectric-barrier discharge reactor

CH₄ reforming of CO₂ reaction for producing synthesis gas (syngas) was performed using dielectric-barrier discharge (DBD) with catalyst. Ni/γ-Al₂O₃ was used as a catalyst. To investigate the effect of reaction temperature, extra heating was applied outside of the plasma reactor. When supplied extra heating, pure syngas could be obtained only at 573 K. It is a noticeable result comparing with pure catalytic reaction or plasma reaction only.
