Performance and Long-Term Stability of Pd/PSS and Pd/Al2O3 Membranes for Hydrogen Separation
The present work is focused on the investigation of the performance and long-term stability of two composite palladium membranes under different operating conditions. One membrane (Pd/porous stainless steel (PSS)) is characterized by a ~10 µm-thick palladium layer on a porous stainless steel substrate, which is pretreated by means of surface modification and oxidation; the other membrane (Pd/Al...
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 کاملTheoretical Performance Evaluation of Inorganic (Non Pd-Based) Membranes for Hydrogen Separation
The aim of this work theoretical study is to theoretically investigate a inorganic membrane assisted purifcation process of an H2-rich stream derived from a conventional methanol steam reforming stage. In particular, a black-box model for multicomponent gas mixture purifcation is dev...
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 کاملModelling of Pd-membranes deformation during hydrogen separation
Pd-membranes used for hydrogen separation work at elevated temperatures under pressure causing plastic deformation of the membranes. The problem is complicated by the fact that these membranes are very thin. Preferable thickness varies between 1 and 5μm. Different mathematical approaches can be used for modelling of this complex situation. Variety of 2D and 3D ABAQUS models are tested for this ...
