This study focuses on the use of a heterogeneous catalyst Ni/Ce_0.58Zr_0.42O₂ 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.

耦合实验和模拟分析研究等离子体催化混合过程中CO2甲烷化的物理参数

这项研究的重点是使用非均相催化剂Ni / Ce _0.58 Zr _0.42 O ₂研究常规催化热加热中的Sabatier反应和介电势垒放电等离子催化过程。其目的是研究血浆条件下Sabatier反应的阈值温度。在等离子体反应器中进行了一系列不同入口流速的实验，以研究反应的稳态温度。为了更准确地估计Sabatier反应的阈值温度，在COMSOLMultiphysics®软件中计算并模拟了催化床与反应器外表面之间的温差。最后，根据实验数据和模拟分析，假设等离子体处理过程中Sabatier反应的阈值温度为116°C。
