Plasma-sorbent systems are a novel technology for single-stage carbon capture and utilization (CCU), where the plasma enables the desorption of CO from a sorbent and the simultaneous conversion to CO. In this study, we test the flexibility of a plasma-sorbent system in a single unit, specifically for sorption-enhanced dry reforming of methane (DRM). The experimental results indicate the selective adsorption of CO by the sorbent zeolite 5A in the first step, and CH addition during the plasma-based desorption of CO enables DRM to various value-added products in the second step, such as H, CO, hydrocarbons, and the byproduct HO. Furthermore, our work also demonstrates that zeolite has the potential to increase the conversion of CO and CH, attributed to its capability to capture HO. Aside from the notable carbon deposition, material analysis shows that the zeolite remains relatively stable under plasma exposure.
等离子体吸附剂系统是一种用于单级碳捕获与利用（CCU）的新技术，其中等离子体能够使吸附剂中的CO解吸并同时转化为CO。在本研究中，我们测试了单个装置中等离子体吸附剂系统的灵活性，特别是用于甲烷吸附增强干重整（DRM）。实验结果表明，第一步中吸附剂5A分子筛对CO具有选择性吸附，第二步中在基于等离子体的CO解吸过程中添加CH可使DRM转化为各种增值产品，如H、CO、碳氢化合物和副产物HO。此外，我们的工作还表明，分子筛有潜力提高CO和CH的转化率，这归因于其捕获HO的能力。除了明显的积碳外，材料分析表明，分子筛在等离子体暴露下仍相对稳定。
