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 pressure and load. 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.
