Catalyst for concentrating hydrogen isotopes and process for producing a support therefor
Patent
·
OSTI ID:6360389
A catalyst is claimed for concentrating hydrogen isotopes for use in performing hydrogen isotopes exchange between gaseous hydrogen and liquid water. The catalyst comprises a support of porous polytetrafluoroethylene having a total specific surface area of 2 to 80 m/sub 2//g as a result of mixing therewith 0.5 to 15% by weight of fluorocarbon or a porous styrene polymer or styrene/divinylbenzene copolymer having a specific surface area of at least 150 m/sub 2//g, and deposited on the support particles of at least one element selected from group VIII of the periodic table. A method for producing a support of porous polytetrafluoroethylene for such catalyst is also disclosed.
