Systematic studies were performed on low-temperature steam conversion or low-temperature
steam reforming (LTSR) of propane in an excess of methane on a Ni-based catalyst. The LTSR of the methane–propane
mixture is a two-stage process involving the irreversible steam conversion of propane into carbon
dioxide and hydrogen and reversible methanation of carbon dioxide. Above ~250°C, the methanation of
carbon dioxide is quasi-equilibrium. The rate of propane conversion during the LTSR of the methane–propane
mixture is first-order based on propane; its activation energy is ~120 kJ/mol and is almost independent
of the methane, carbon dioxide, hydrogen, and steam concentrations. This very simple macrokinetic scheme
allows us to correctly describe the experimental data and predict the temperature and flow rate of the mixture
at which complete conversion of propane is achieved.
