Non-Pd BCC alloy membranes for industrial hydrogen separation

Composition and operation of hydrogen-selective amorphous alloy membranes

We prepared the melt-spun (Ni0:6Nb0:4)100� xZrx (x ¼ 0 to 40 at%) and other amorphous alloy membranes and examined the permeation of hydrogen through those alloy membranes. The interatomic spacing in the Ni–Nb–Zr amorphous structure increased with increasing Zr content. The crystallization temperature of the Ni–Nb–Zr amorphous alloys decreased with increasing Zr content. The hydrogen flow increased with an increase of the temperature or the difference in the square-roots of hydrogen pressures across the membrane, � ffiffiffi p . At relatively higher temperature up to 673 K or at relatively higher hydrogen pressure difference, � ffiffiffi p up to 550 Pa 1=2 , the hydrogen flow was more strictly

Hydrogen Permeation Characteristics of Melt-Spun Ni-Nb-Zr Amorphous Alloy Membranes

Improvements are disclosed for fabrication of composite hydrogen transport membranes, which are used for extraction of hydrogen from gas mixtures. Methods are described for supporting and re-enforcing layers of metals and metal alloys which have high permeability for hydrogen but which are either too thin to be self supporting, too weak to resist desired differential pressures across the membrane, or which become embrittled by hydrogen. In order to minimize stress at internal interfaces, which can lead to formation of dislocations and initiations of cracks, the support material is chosen so as to be lattice matched to the metals and metal alloys. Preferred metals with high permeability for hydrogen include vanadium, niobium, tantalum, palladium, and alloys thereof. In one embodiment, a porous support matrix is fabricated first, and then the pores are blocked by metals and metal alloys which are permeable to hydrogen. In a second embodiment, powders of the preferred metal are first sintered together to form a porous metal matrix, and the pores of the metal matrix are then blocked with materials which make the membrane impervious to gases other than hydrogen. In a third embodiment, cermets (ceramic-metals) are fabricated by sintering together powders of the preferred metals with powders of lattice-matched ceramic to make a dense material impervious to gases other than hydrogen.
