“…However, in realistic applications, scenarios often involve the presence of contaminants or, conversely, low CO 2 concentrations, necessitating enrichment through processes involving adsorbents, as seen in DAC. Several reported studies have focused on addressing these challenges, including not only the effect of impurities but also the combination with sorbents in plasma-based CCU in a one-stage ,− and double-stage configuration. − Yoshida et al studied the desorption of CO 2 when the sorbent material is placed inside the plasma zone. They even demonstrated faster desorption with plasma than with a thermal approach, and they attributed this effect to the interaction of the electrons and reactive species in the plasma with the sorbent material.…”

Plasma−sorbent systems are a novel technology for single-stage carbon capture and utilization (CCU), where the plasma enables the desorption of CO 2 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 2 by the sorbent zeolite 5A in the first step, and CH 4 addition during the plasma-based desorption of CO 2 enables DRM to various value-added products in the second step, such as H 2 , CO, hydrocarbons, and the byproduct H 2 O. Furthermore, our work also demonstrates that zeolite has the potential to increase the conversion of CO 2 and CH 4 , attributed to its capability to capture H 2 O. Aside from the notable carbon deposition, material analysis shows that the zeolite remains relatively stable under plasma exposure.
