Patent ID: 7927578

Claim:
A method for separation of molecular hydrogen from a gaseous mixture containing said molecular hydrogen comprising the steps of: providing a dense mixed oxide ion/electronic/hydrogen atom conducting separator having a feed side and a permeate side inside a gasification reactor; providing said gaseous mixture to said feed side of said separator, said gaseous mixture comprising a synthesis gas produced by gasification of a solid fuel in the gasification reactor; converting at least a portion of said molecular hydrogen to hydrogen atoms; providing a plurality of oxide ions on said permeate side of said separator; transferring said hydrogen atoms from said feed side through said separator to said permeate side of said separator and transferring said oxide ions from said permeate side through said separator to said feed side, generating electrons on said feed side for transfer to said permeate side; transferring said electrons from said feed side through said separator to said permeate side; and converting said hydrogen atoms on said permeate side of said separator to molecular hydrogen.
