In the CH₄/CO₂ reforming reaction, when Dielectric Barrier Discharge (DBD) is superimposed on the Ni/ Al₂O₃ catalyst packed bed, the conversion rate increases significantly for both CH₄ and CO₂ under the constant catalyst temperature. Dissociation of a stable C-H bond is known to be the rate-liming step; therefore, accelerating the CH₄ conversion rate by DBD is extremely useful for increasing the overall reaction rate. In this paper, the kinetic analysis of the plasma catalysis of CH₄/CO₂ reforming reaction was carried out in order to identify the key step for nonthermal plasma induced reaction enhancement mechanism.
