Transition metal modified Ce-based catalysts for low concentration methane combustion in porous media burners

Key Points

• The aim is to improve self-sustaining combustion of low concentration methane using modified Ce-based catalysts.
• Utilized Ce-based catalysts with transition metals (Mn, Fe, Co) as dopants.
• Employed open-cell support materials for the catalysts in experimental setups.
• Conducted combustion tests to assess performance at low methane concentrations.
• Catalysts showed enhanced activity for methane combustion at low concentrations.
• Doping with transition metals improved combustion efficiency and stability.
• Optimal performance achieved with specific dopants in porous media configurations.
