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.

为评价核聚变堆固体增殖包层氚回收系统干燥器中加入催化剂后的氚回收效率，探讨了亲水性催化剂替代吸附剂的应用。合成沸石作为催化剂的载体，是通过阳离子的置换来改变其性质的。本文研究了具有交换阳离子的丝光沸石型沸石（莫尔）作为催化剂载体对同位素交换反应的影响。目前，对于氢同位素交换催化剂，不能避免使用贵金属。Pt催化剂的活性大于Pd催化剂。并且，已经观察到其载体是与第1族离子进行阳离子交换的莫尔的Pt催化剂的活性变得大于与第2族离子进行阳离子交换的莫尔的Pt催化剂的活性的趋势。催化剂的活性与载体的BET比表面积大小有关。
