Key Points

Investigate the impact of a spiral catalyst and swirl flow enhancement on thermal management and operational longevity during e-methanation.
Designed a spiral catalyst reactor to induce enhanced swirl flow for improved reaction conversion.
Evaluated long-term catalytic stability and durability at 350 °C under a continuous 5 W power input over a 50-hour duration.
Achieved stable and continuous methane production throughout the entire 50-hour test period at 350 °C.
Demonstrated robust catalyst durability and reduced energy requirements at an operating power of 5 W driven by enhanced swirl flow dynamics.

Implication

Laboratory study demonstrates sustained methane production across 50 hours using a spiral catalyst with enhanced swirl flow, indicating robust durability and energy efficiency.
