Abstract

First, modeling of the carbon dioxide reforming reaction (CO₂RR) mechanism was carried out by the chemical affinity values of the individual elementary reactions which would be involved in the overall reaction. The chemical affinity values were obtained from a composition of an outlet stream passed through a catalyst bed. The catalysts used were Ni, Ru, Rh, Pd and Pt supported on MgO. As a result, the decomposition of CH₄ to give carbonaceous deposits and H₂ was the slowest step in CO₂RR. Then, a separate production of H₂ and CO over Ni catalysts from an alternate stream of CH₄ and CO₂ was proved by the use of a flow system equipped with two reactors in parallel, two selector valves, and two gas reservoirs. As a result, such mixtures were obtained as H₂(74%)+CH₄(18%) and CO(71%)+CO₂(17%) when Ni/α-Al₂O₃ was used as a catalyst.
