Oxygen Separation Ceramic Membranes

For more than a decade there has been considerable interest in dense inorganic ceramic oxygen separation membranes as they offer a potentially attractive means of producing high purity oxygen from air for use in the next generation of industrial processes and clean energy applications.

Oxygen separation ceramic membranes. These membranes are 100 selective to oxygen resulting in very high purity oxygen and are competitive with cryo genic separation methods. It is also considered as a cheaper. The high selectivity is related to the mechanism of ion transport. More recently dense ceramic membranes fabricated from ionic conductors have been proposed as active membranes for the high temperature separation of oxygen from air for a variety of purposes.

Ceramic membranes for oxygen separation from air have attracted significant attention because the ceramic membrane operate vias oxygen ion diffusio n through dense solids and show theoretically 100 selectivity of oxygen separation. In a ceramic membrane oxygen separation system oxygen molecules in air are dissociated and reduced to oxygen ions at the mem. Ceramic mixed conducting membranes separate oxygen with perfect selectivity via ionic oxygen transport by vacancy or interstitial diffusion through the crystalline material. Ceramic membranes separate oxygen through a mechanism called ion transport whereby oxygen ions flow across a membrane drawn to the side of the membrane with less oxygen.
