Emissions of methane to the atmosphere are deemed by many to pose environmental problems. Conversion of methane to carbon dioxide through combustion reduces greenhouse gasses and can provide a source of energy. Catalytic combustion is a viable option for oxidation of lean methane streams. Lean methane mixtures can be…
