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.
