Thermal effects on methane steam reforming process were analyzed, in a Pd‐Ag (23wt%) membrane reactor as a function of several parameters, such as temperature, reactant and sweep‐gas flow rate, and reactant molar ratio. Heat transfer from the oven was very important for the outlet methane conversion, which also depends on the temperature profile along the reactor. In particular, when the reactant flow rate was high the conversion degree decreased because the energy supplied was not sufficient to maintain the temperature in the reactor. A non‐isothermal mathematical model was presented which reproduced the experimental data.
