Hydrogen separation

Palladium alloy composite membranes for hydrogen separation have been fabricated on a porous stainless steel (SS) support by the vacuum electrodeposition and laminating procedure of thin palladium alloy film less than 25 mm. In spite of the formation of an alloy with copper, the brittleness of the p

Composite Pd alloy membranes have been investigated as a means of reducing the membrane cost and improving H2 flux. Recently, we have been able to dramatically reduce the thickness of our Pd alloy membranes to approximately one micron. This is significant because at this thickness, it is the cost of

Zeolite A membranes have been synthesised by secondary growth on the surface of macroporous "-alumina and stainless steel tubular supports, previously seeded with zeolite A crystals. The membranes thus obtained were used in the separation of H2/N2 and H2/C3H8 mixtures. Stainless steel supports appea
