Development of Palladium-Alloy Membranes for Hydrogen Separation and Purification
This paper summarizes R&D activities and progress at NORAM Engineering and the University of British Columbia (UBC) on preparation and testing of thin palladium-based membranes and their applications. Most of these activities were carried out internally at NORAM, some jointly with UBC and their spin-off company, Membrane Reactor Technology (MRT) through a wide range of projects. Key results out...
متن کاملSeparation of Hydrogen Isotopes ELECTROLYTIC MIGRATION THROUGH A PALLADIUM MEMBRANE
With the increasing importance of “ heavy water” as a moderator in nuclear reactors there arises a pressing need for a more efficient method of separating hydrogen isotopes. In a report by 0. N. Salmon to the U.S. Atomic Energy Commission (AEC Research and Development Report KAPL 1272) a process is described which aims to improve the method of separation by the electrolysis of water. This proce...
متن کاملMicrofabrication of Palladium–Silver Alloy Membranes for Hydrogen Separation
In this paper, a process for the microfabrication of a wafer-scale palladium—silver alloy membrane (Pd–Ag) is presented. Pd–Ag alloy films containing 23 wt% Ag were prepared by co-sputtering from pure Pd and Ag targets. The films were deposited on the unetched side of a 110 -oriented silicon wafer in which deep grooves were etched in a concentrated KOH solution, leaving silicon membranes with a...
متن کاملMicromachined Palladium - Silver Alloy Membranes for Hydrogen Separation
This paper presents wafer-scale palladium silver alloy membranes, fabricated with a sequence of wellknown thin film and silicon micromachining techniques. The membranes have been tested in a gas permeation system to determine the hydrogen permeability and hydrogen selectivity. Typical flow rates of 1 mol H2 /m.s have been measured with a minimal selectivity of 1500 for H2/He. The membranes have...
متن کاملPreparation of palladium–silver alloy films by a dual-sputtering technique and its application in hydrogen separation membrane
Submicron thick palladium–silver alloy films with 23 wt.% of silver (Pd–Ag23) have been synthesized by simultaneous sputtering from pure targets of Pd and Ag. Full characterization of the deposited films was performed by using X-ray photoelectron spectroscopy, highresolution scanning electron microscopy, high-resolution transmission electron microscopy, and X-ray diffraction. The analytical res...
