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 کاملSynthesis of Supported Palladium Catalysts
The synthesis of supported palladium (Pd) catalysts is reviewed with emphasis on the chemistry of catalyst synthesis, oxidic and carbon support properties and case studies in the period 1990-2000. For the application of Pd onto oxidic supports aqueous precursor solutions are frequently used. The charge of the Pd precursor and the iso-electric point of the support are important properties since ...
متن کاملRecovery of Palladium from Spent Activated Carbon-Supported Palladium Catalysts
TÜBİTAK Marmara Research Center, Chemistry Institute, 41470 Gebze, Kocaeli, Turkey Email: [email protected] Activated carbon-supported palladium catalysts are liable to progressive deactivation even in the absence of any gaseous contaminants during the oxidation of hydrogen under ambient conditions. The high value of palladium coupled with environmental considerations means that n...
متن کاملSynthesis and Characterization of a Novel Nanoporous Composite Based on Elemental Sulfur and Graphitic Mesoporous Carbon
A novel sulfur nanocomposite was fabricated based on graphitic mesoporous carbon.The graphitic mesoporous carbon was synthesized using sucrose as carbon precursor, nano CaCO3 as a hard template and nickel nitrate as graphitization catalyst. The structural properties of the prepared material were characterized using powder X-Ray Diffraction (XRD), N2-adsorption/de...
