Development Of Ceramic Membranes For Hydrogen Separation

The purpose of this project is to develop an efficient separation system that can separate hydrogen from other gases in coal-derived synthesis gas.

The nature of the material is such that molecules of hydrogen - which are significantly smaller than molecules of carbon monoxide, carbon dioxide, and hydrocarbon gases - pass through the porous material and away from other gases.

The ability to separate and collect hydrogen for use as fuel for fuel cells or for use in petroleum refinery catalytic crackers will greatly add to the economical benefits of integrated gasification combined cycle systems.
