Numbering up and sizing up gliding arc reactors to enhance the plasma-based synthesis of NO .

Non-thermal plasma-based NO synthesis from ambient air is receiving an increasing amount of interest for its potential in small-scale, sustainable fertilizer production. Nevertheless, most reported research focuses on lab-scale systems and a single reactor with limited production. In this work, two gliding arc reactors (GARs) with 2 mm discharge gaps were connected in series or in parallel to explore strategies for scaling up the productivity.

Sorption-Enhanced Dry Reforming of Methane in a DBD Plasma Reactor for Single-Stage Carbon Capture and Utilization.

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.
