Abstract:
A system for removing hydrogen and its isotopes from an enclosed space, comprising:a) an enclosed space having an atmosphere contained therein; andb) a hydrogen getter composition contained within said enclosed space, said getter composition comprising:i) an organic polymer, said organic polymer comprising a plurality of repeating monomer units, said units having up to six side branches, said side branches further comprising C.sub.1 -C.sub.8 alkyl that contain or are substituted with one or more functionalities selected from the group consisting of C.sub.2 -C.sub.8 alkene, C.sub.2 -C.sub.8 alkyne, C.sub.1 -C.sub.8 ether, C.sub.1 -C.sub.8 alcohol, C.sub.1 -C.sub.8 ester, phenyl, C.sub.1 -C.sub.10 anhydride, C.sub.1 -C.sub.8 isocyanate, C.sub.1 -C.sub.8 ketone, C.sub.1 -C.sub.8 epoxide, and C.sub.1 -C.sub.8 carboxylic acid such that each said unit contains at least one carbon-carbon double bond;ii) a hydrogenation catalyst consisting essentially of a noble metal catalyst and an inert catalyst support material, said hydrogenation catalyst distributed throughout said getter composition wherein said double bonds and said noble metal catalyst are in reactive association; andiii) an inert diluent, said diluent selected from the list consisting of carbon black powders, mineral powders, salts, thixotropic agents and combinations thereof.
