Membrane-based processes have the potential to overcome the limitations of conventional hydrogen separation techniques such as high energy consumption and environmental concerns. Natural zeolite membranes have recently been shown to demonstrate apparent molecular sieving of H2 from H2/CO2...

High-purity oxygen above 99.0% is required in many medical and industrial applications such as the pharmaceutical and aerospace applications. Due to the similar physical properties of oxygen and argon, this separation is very challenging. Adsorption separation techniques are more preferable to...

Separating hydrogen and carbon dioxide from syngas is a necessary step for many industrial processes. Membrane separations are an attractive solution as they can operate at process temperatures (200-500 °C) and operate with a simple process. Pure thermally stable (up to 600 °C) clinoptilolite...
