This study focuses on the use of a heterogeneous catalyst Ni/Ce 0.58 Zr 0.42 O 2 to study the Sabatier reaction in conventional catalytic thermal heating and the dielectric barrier discharge plasma‐catalytic process. Its aim is to study the threshold temperature of the Sabatier reaction in plasma conditions. A set of experiments with different inlet flow rates is carried out in a plasma reactor to investigate the steady‐state temperature of the reaction. To estimate the threshold temperature of the Sabatier reaction more accurately, the temperature difference between the catalytic bed and the external surface of the reactor is calculated and simulated in COMSOL Multiphysics® software. Finally, the threshold temperature of the Sabatier reaction during plasma processing is assumed to be 116°C, based on the experimental data and simulation analysis.
