The use of catalysts to improve the exchange kinetics between hydrogen isotopes in the gas phase and that in the solid phase was investigated. Granules of alumina, silica and molecular sieve were coated with platinum as the catalyst. The granules saturated with water at room humidity were packed in a 2-cm diameter column for isotope exchange tests. Deuterium and protium were alternately fed through the column at a constant rate. Isotope concentration in column effluent was monitored to generate isotope break-through curves. The curves were analyzed to produce information on the kinetics and capacity of the material. The results showed that all materials tested provided some extent of isotope exchange but some were superior both in kinetics and capacity. This paper will present the test results.
