Abstract
A method of manufacturing such gas separation membrane system that includes applying to a surface of a porous substrate a layer of a nanopowder of a gas-selective metal and, thereafter, heat-treating the resultant surface treated porous substrate to yield a heat-treated and surface-treated porous substrate suitable for use as a gas separation membrane system.
Claims31
A method of making a gas separation membrane, wherein said method comprises:
- applying to a surface of a porous substrate a layer of a nanopowder, comprising nanoparticles of a gas-selective metal, to provide a surface treated porous substrate;
- and
- heating said surface treated coated porous substrate to thereby provide a heat treated surface treated porous substrate.
A gas separation membrane system, comprising:
- a porous substrate, having a surface that is treated with a layer of a nanopowder, wherein said nanopowder comprises nanoparticles of a gas-selective metal, to thereby provide a surface-treated porous substrate, and wherein said surface-treated porous substrate is heat-treated to provide said gas separation membrane system.
