Low-Cost, Robust Ceramic Membranes for Gas Separation

Ceramic membranes offer great potential for industrial gas separation. While ceramic membranes can improve the productivity for many reactions and separations in the chemicals and refining industries, they are costly.

A low-cost, robust ceramic membrane has overcome the cost barrier and targets applications involving hydrogen production, water and energy recovery from fuel, and CO2 removal in natural gas processing. Significant energy savings are possible because the new membrane eliminates cooling prior to gas separation. In addition, this low-cost membrane is currently under consideration as substrate for a wide range of thin films that can be used in industrial gas separations; and without the gas separating layer, the membrane has been used commercially for a wide range
of liquid-phase separations.
