Abstract

CO2 behavior in the carbon dioxide reforming of methane over supported KNiCa catalyst was investigated by using 'in-situ' FT-IR, CO2-TPD and pulse reaction method. The role of alkali metals on the catalyst was to improve catalyst stability through a high surface coverage of adsorbed CO2 and formation of surface carbonates. It was demonstrated that the oxidation step of surface carbon with adsorbed CO2 or surface oxygen on the catalyst contributes to high catalyst stability by the effective removal of surface carbon species.
