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.
