Syndiotactic polypropylene copolymer membranes and their performance for oxygen separation

Practical Techniques for Improving the Performance of Polymeric Membranes and Processes for Protein Separation and Purification

Protein separation and purification technologies play an essential role in various industries including but not limited to pharmaceuticals, dairy as well as the food sector. Accordingly, a wide variety of techniques such as chromatography and electrophoresis has been developed and utilized extensively over the years for this purpose. Despite their widespread acceptance, conventiona...

Supported Dense Ceramic Membranes for Oxygen Separation

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...

Multichannel Mixed-Conducting Hollow Fiber Membranes for Oxygen Separation

A multichannel mixed-conducting hollow fiber (MMCHF) membrane, 0.5 wt % Nb2O5-doped SrCo0.8 Fe0.2O3-d (SCFNb), has been successfully prepared by phase inversion and sintering technique. The crystalline structure, morphology, sintering behavior, breaking load, and oxygen permeability of the MMCHF membrane were studied systematically. The MMCHF membrane with porous-dense asymmetrical microstructu...
