The performances of the catalysts for CH4–CO2 reforming were investigated at Received in revised form 11 August 2015 800 °C under atmospheric pressure and gas hourly space velocity (GHSV) of 60 L/(hgcat). Two representative Accepted 12 August 2015 catalysts which contained 0% and 10% CeZrO2 were further reacted at 900 °C to preliminarily study the feasibility Available online xxxx of establishing a balance between carbon deposition and elimination on the two catalysts.
