In‐Liquid Plasma Catalysis: Tools for Sustainable H₂‐free Heavy Oils Upgrading

ChemistrySelect, Journal Year: 2024, Volume and Issue: 9(3)

Published: Jan. 16, 2024

Abstract Non‐thermal plasma (NTP) catalysis, mirroring the trend towards non‐conventional electron‐mediated molecular activation, unfolds novel routes for chemical reactions. Operating at ambient pressure, lower temperatures, and energized by electricity that can powered renewable sources, NTP offers a cost‐effective efficient means of sustainable fuel production. This approach has potential to revolutionize oil gas industry, meeting current energy demands while circumventing challenges posed conventional thermal catalysis processes, thereby enhancing environmental sustainability security. Through an exploration synergistic effects between plasma, hydrocarbon molecules, this concept paper emphasizes significant advancements made in in‐liquid strategies production from heavy upgrading. We also provide insights into heterogeneous catalyst design role as additional achieving solutions. The prospects emphasizing its transformative shaping future, are discussed.

Role of Reducible and Mobile Oxygens in Methane Partial Oxidation Within a Post‐Plasma Catalytic System

ChemistrySelect, Journal Year: 2025, Volume and Issue: 10(12)

Published: March 1, 2025

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, catalyst oxygen species were evaluated for optimizing plasma‐catalytic performance. Key findings indicate that extended O 2 contact time, reduced CH 4 water addition to feed, use mobile oxygen‐enriched catalyst, is NaW/Al, positively influence extent partial oxidation. Notably, NaW/Al plays role improving yields products (CH 3 OH, HCOH, HCOOH) can be replenished through calcination within PPC
