SOI-Supported Microdevice for Hydrogen Purification Using Palladium–Silver Membranes
High-purity hydrogen continues to receive attention as a promising energy source for fuel cells in portable power applications. On-demand hydrogen generation via fuel reforming offers a convenient alternative to hydrogen storage, but the concomitant CO generation is deleterious to the fuel cell catalyst. Of the possible hydrogen purification options, palladium membranes allow a compact design s...
متن کاملDevelopment 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 کاملPlasticization-enhanced hydrogen purification using polymeric membranes.
Polymer membranes are attractive for molecular-scale separations such as hydrogen purification because of inherently low energy requirements. However, membrane materials with outstanding hydrogen separation performance in feed streams containing high-pressure carbon dioxide and impurities such as hydrogen sulfide and water are not available. We report highly permeable, reverse-selective membran...
متن کاملHighly permeable supported γ-alumina membranes for water purification
Nanofiltration with inorganic meso-porous membranes is being considered more and more for water purification applications. For specific applications inorganic membranes may have advantages over organic polymer-based membranes due to their rigid pore structure, and thermochemical stability. However, the permeability and, partly through that, the permselectivity of inorganic membranes need to be ...
متن کاملSupported Biomimetic Membranes for Pressure-Driven Water Purification
The desalination technology of choice today is reverse osmosis (RO). In this process saline water is forced using mechanical pressure across a membrane that can selectively pass water and reject almost all ions and most neutral molecules. Reverse osmosis proved to be robust and most energy efficient technology that can be exploited for a wide range of water sources. Nevertheless water desalinat...
