The chemical looping reforming and combustion of methane have attracted increasing interest as processes for clean energy syngas production, with potential to reduce carbon dioxide emissions. Previous literature on the development oxygen carriers evidenced effects that availability exerts selectivity oxidation reaction. In present paper, we evaluate performance chromite sand (Chro), cerium (CeO2), mixed cerium–copper oxide (Ce–Cu) either or according their availability. oxides are tested in 2 5 min reduction intervals a CH4/N2 mixture (5, 10 20% vol.) followed by regeneration O2/N2 (3, 5, 21% vol.), redox cycles conducted at 850 °C 950 °C. obtained rank towards complete CH4 is Ce–Cu > CeO2 Chro. Another relevant finding role degree carrier conversion promoting partial total oxidation. particular, CO2 markedly decreases conversion, disclosing new strategies process design optimization controlling degree.
