CO Methanation on Rh/Al2O3: Dynamic in-Situ FTIR Experiments and Steady-State Measurements

CO hydrogenation over a 1%Rh/γ-Al₂O₃ catalyst was studied at 200-300ºC. Dynamic and steady-state in-situ FTIR measurements were used to scrutiny the catalyst surface and explain its kinetic performance. It is proposed a mechanism in which the C-O bond dissociation is assisted by H-addition and H₂ and CO adsorptions are quasi-equilibrated.
