     the performance of a ru/sio2 catalyst for methane steam reforming at 450–550 °c is studied in the present. these conditions are suitable for coupling the fixed-bed reactor with a hydrogen-selective membrane for hydrogen recovery, with the subsequent equilibrium shift. a reaction mechanism based on the dissociative adsorption of steam and methane has been proposed (from a total of six possible mechanisms compared), in terms of the statistical analysis of reaction data obtained at different temperatures and contact times in an integral, lab-scale reactor.

    the proposed model shows that hydrogen inhibition plays an important role in the reaction. finally, the ru/sio2 catalyst prepared in this work is found to be one of the most active catalysts, among other ru-based catalysts reported in the literature.
