Role of Reducible and Mobile Oxygens in Methane Partial Oxidation Within a Post‐Plasma Catalytic System
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 O 2 contact time, reduced CH 4 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 (CH 3 OH, HCOH, and HCOOH) and can be replenished through calcination within the PPC system.
