| Research Abstract |
In this study, to evaluate tritium recovery efficiency when catalytic function is added to the dryer of tritium recovery system for solid breeder blanket of nuclear fusion reactor, application of hydrophilic catalyst instead of adsorbent is discussed. Synthetic zeolite used as a carrier of catalyst changes its property by replacing its cation to other one. In this work, influence on isotopic exchange reaction has been investigated when mordenite type zeolite (MOR) having exchanged cation is used as a carrier of catalyst. Presently, use of noble metal cannot be avoided for hydrogen isotopic exchange catalyst. Activity of Pt-catalyst became larger than Pd-catalyst. And, the tendency that the activity of the Pt-catalyst whose carrier is cation-exchanged MOR with group 1 ion becomes larger than MOR with group 2 ion has been observed. And, it seems that the catalytic activity depend on the order of BET surface area of the carrier.
