Abstract
A method and apparatus for separation of H2 gas from a gaseous mixture utilizing an H2 gas permeable metallic membrane supported directly on a porous substrate made up of at least one porous polymeric hollow fiber. In accordance with one preferred embodiment, the porous substrate is made up of a plurality of porous polymeric hollow fibers, forming a porous hollow fiber membrane. In accordance with one embodiment, a cooling fluid is disposed in contact with the hollow fiber, thereby enabling advantageous operation of the H2 gas separation process at elevated temperatures in the range of about 200° F. to about 800° F.
Claims11
An apparatus for H2 separation comprising:
- an H2 gas permeable metallic membrane supported directly on a porous substrate comprising at least one porous hollow fiber having two open ends;
- and
- membrane cooling means for liquid cooling said at least one hollow fiber.
A method for separation of H2 gas from a mixture comprising said H2 gas comprising the steps of:
- contacting a composite membrane comprising an H2 gas permeable metallic membrane disposed directly on at least one porous hollow fiber substrate having two open ends with said mixture on a metallic membrane side of said composite membrane at a temperature in a range of about 200° F. to about 800° F., whereby said H2 gas permeates through said metallic membrane to a permeate side of said metallic membrane;
- and
- contacting one of an interior surface and an exterior surface of said at least one porous hollow fiber substrate with a liquid cooling fluid.
