Temperature programmed oxidation combined with mass-spectrometry(TPO-MS) technique has been used to investigate the burning of carbon deposited on the Co/Al₂O₃ catalysts during reforming of methane with CO₂. Obvious coke and carbon deposition sites were found on the 13%Co/Al₂O₃, while on the 8%Co/Al₂O₃ only coke deposition site. The total amount of carbon and coke deposites was much greater on the surface of 13%Co/Al₂O₃. It is considered the reason that 13%Co/Al₂O₃ catalyst showed better catalytic activity and stability than the other one.
