Catalytic methane decomposition on Fe/γ-Al₂O₃ to generate hydrogen is kinetically discussed utilizing TG experiments. Effect of hydrogen in the reaction gas should be examined for hydrogen production. It was found that a significant deactivation of the catalyst is observed in the pure CH₄ atmosphere, and hydrogen in the reaction gas can suppress the deactivation of the catalyst significantly, Steady state activity could be obtained at 650 °C in the presence of hydrogen, and this phenomenon is significantly dependent on the reaction temperature. Equilibrium constants could be determined using non-isothermal experiments. Initial reaction rate is also examined, and the activation energy of the rate constant could be determined to be 69 kJ/mol.
