We present a confined atmospheric pressure glow discharge plasma reactor, with very good performance towards dry reforming of methane, i.e., CO₂ and CH₄ conversion of 64 % and 94 %, respectively, at an energy cost of 3.5–4 eV/molecule (or 14–16 kJ/L). This excellent performance is among the best reported up to now for all types of plasma reactors in literature, and is due to the confinement of the plasma, which maximizes the fraction of gas passing through the active plasma region. The main product formed is syngas, with H₂O and C₂H₂ as by-products. We developed a quasi-1D chemical kinetics model, showing good agreement with the experimental results, which provides a thorough insight in the reaction pathways underlying the conversion of CO₂ and CH₄ and the formation of the different products.

我们提出了一个密闭的大气压辉光放电等离子体反应器，对甲烷的干重整具有非常好的性能，即 CO ₂和 CH _{4 的}转化率分别为 64% 和 94%，能量成本为 3.5-4 eV/分子（或 14–16 kJ/L）。这种出色的性能是迄今为止文献中所有类型的等离子体反应器所报道的最好的性能之一，这是由于等离子体的限制，使通过活性等离子体区域的气体比例最大化。形成的主要产品是合成气，含有 H ₂ O 和 C ₂ H ₂作为副产品。我们开发了一个准一维化学动力学模型，显示出与实验结果的良好一致性，它提供了对 CO ₂和 CH ₄转化以及不同产物形成的反应途径的全面了解。
