Abstract
This study examines methane oxidation in a post-plasma catalysis (PPC) system. Using dielectric barrier discharge plasma with metal oxide-supported catalysts (Cu/Al, Ni/Al, Fe/Al, and NaW/Al), the effects of reactant feed type, composition, and catalyst oxygen species were evaluated for optimizing plasma-catalytic performance. Key findings indicate that extended O2 contact time, reduced CH4 contact time, water addition to the feed, and the use of mobile oxygen-enriched catalyst, that is NaW/Al, positively influence the extent of partial oxidation. Notably, the mobile oxygen in NaW/Al plays a role in improving the yields of partial oxidation products (CH3OH, HCOH, and HCOOH) and can be replenished through calcination within the PPC system.
