Catalytic syngas production from greenhouse gasses: Performance comparison of Ru-Al2O3 and Rh-CeO2 catalysts

- Carbon formation negligibly influenced catalytic activity.
- Ru-Al2O3 deactivation was caused by metallic cluster sintering.
- Rh-CeO2 catalyst exhibited extraordinary stability with negligible deactivation.
- H2/CO molar ratio can be increased by using feed stream with CH4/CO2 ratio well above 1.
- RWGS reaction was near thermodynamic equilibrium during CH4-CO2 reforming.
