Hydrogen-rich syngas generation through microwave plasma reforming of greenhouse gases

Plasma Catalysis for Hydrogen Production: A Bright Future for Decarbonization

“…More recently, a similar volcano curve in H 2 production was observed in an atmospheric pressure microwave plasma torch for DRM (Figure ). Akande et al reported the hydrogen production rate and H 2 energy yield peaked at 1672 and 41.8 g (H 2 )/kWh, respectively, at an optimal flow rate of 140 L/min. The authors attributed the enhanced H 2 production rate to the plasma flame elongation as the flow rate increased from 120 to 140 L/min .…”

The authors attributed the enhanced H 2 production rate to the plasma flame elongation as the flow rate increased from 120 to 140 L/min . Given this, it is worth mentioning that achieving both higher hydrogen production and enhanced energy efficiency simultaneously requires careful consideration of an appropriate SEI in the plasma system.…”
