Abstract

Describes results of a numerical and experimental study to evaluate the reactant bypass flow in a catalytic plate reactor with a coated wire mesh catalyst for steam reforming of methane for hydrogen generation. Bypass of unconverted methane is evaluated under different wire mesh catalyst width to reactor duct width ratios.

The study improves the understanding of the underlying transport phenomena in these reactors and shows that the flow maldistribution in a catalytic plate reactor using a coated wire mesh has to be considered.
