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

ABSTRACT: Non-thermal plasma-based NO _x 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. A single GAR with an enlarged discharge gap of 4 mm was also investigated for comparison. Operation parameters such as flow rate, discharge power & mode, and effective residence time were tested. The NO _x concentration increased for all configurations with an increase in specific energy input (SEI), and effective
