Surface Reaction Kinetics for Oxidation and Reforming of H2, CO, and CH4 over Nickel-based Catalysts

An experimental and kinetic modeling study of H2 and CO oxidation, as well as conversion of methane under oxidative and reforming conditions over nickel-based catalyst is presented. The numerical model is based on a newly developed surface reaction mechanism consisting of 52 elementary-steps reactions with 14 surface and 6 gas-phase species. The mechanism was evaluated against experimental data at varying operating conditions performed in this study and also taken from literature.
