Abstract
A method of making a gas separation membrane system by providing a porous support material having deposited thereon a metal membrane layer and imposing upon the surface thereof certain surface characteristics that provide for surface activation that enhances the placement thereon of a subsequent metal membrane layer. The gas separation membrane system is useful in the separation of hydrogen from hydrogen-containing gas streams.
Claims10
A system for making a composite gas separation module, wherein said system comprises:
- a porous support having a metal membrane layer thereon with a surface;
- means for imposing onto said surface and said metal membrane layer a surface morphology that provides for an activated surface having enhanced activation properties for the placement thereon of a subsequent metal membrane layer;
- means for placing said subsequent metal membrane layer upon said activated surface;
- and
- means for annealing said subsequent metal membrane layer to provide an annealed metal layer.
