Palladium Membranes
RTI engineers are developing membranes for separating hydrogen from syngas produced by fossil fuel gasification. Our palladium-silver alloy/ceramic composite membranes have high selectivity and flux rate for hydrogen. Because these metal membranes can operate in higher temperature gas streams than do the copolymer membranes, they avoid thermal penalties associated with cooling the syngas down to temperatures suitable for conventional polymer membranes.
Using RTI's membrane reactor process, carbon dioxide can be separated from hydrogen as a part of the fuel-reforming process, eliminating the need for an additional carbon dioxide separation step.
