-Methanation with a spiral catalyst: optimized thermal management and long-term stability.

This study explores the development of a Joule-heated reaction field utilizing an electrically driven spiral-shaped catalyst for efficient CO methanation. Infrared thermal imaging in an uninsulated reactor reveals a rapid and uniform temperature rise along the spiral structure. With a 10 W input, CO conversion reached 80%, while 75% conversion was maintained even at 5 W.
