Abstract

The kinetics of the methane dry (CO₂) reforming over the SmCoO₃ was investigated in the temperature ranged 973–1073 K by varying the CH₄ and CO₂ partial pressures. Based on detailed study of the reaction mechanism, a mechanistic model is proposed from which a kinetic model is derived. The mechanistic pattern assumes adsorption of CH₄ on reduced Co, followed by methane cracking and carbon deposition. CO₂ reacts with Sm₂O₃ to form Sm₂O₂CO₃ and the oxycarbonates react with carbon to produce CO. The power law and Langmuir–Hinshelwood kinetic model which is established on this mechanism were able to forecast the kinetic results.
