Abstract

Fuel cell powered vehicles with on-board reforming need compact and lightweight components. A membrane reactor that combines hydrogen permeable membranes with a methanol steam reformer promises considerable weight and space savings. Its dense metal membranes produce high-purity hydrogen over a wide range of pressures and loads. The selective removal of hydrogen yields methanol and CO conversions that are higher than the equilibrium conversion in a conventional reactor. Results with three different metal membranes in a membrane reactor for steam reforming of methanol are presented. A mathematical model accurately describes the measured performance of the membrane reactor and allows predictions for other values of the process parameters.
