内容記述タイプ Abstract
内容記述 It is known that the chemical forms of tritium released from a
ceramic breeder blanket are hydrogen form and water form.
To recover tritiated water vapor, adoption of dryer that is
packed column of synthetic zeolite has been proposed. On
the other hand, synthetic zeolite is often used as a support
of precious metal catalyst. Such catalysts usually have a
capability of hydrogen isotope exchange between gas and
water vapor. If this catalyst is used to dryer, the dryer may
obtain a preferable function for tritium recovery by isotopic
exchange reaction. To assess such functions, reaction rate
should be estimated. The results of water adsorption
experiment on cation-exchanged mordenite-type zeolite
suggested the possibility that state of adsorbed water varied
by exchanged cation. So, in this work, precious metal
catalyst basedon cation-exchanged mordenite was
prepared, and the reaction rate of chemical exchange
between hydrogen and tritiated water was investigated
under temperature range between 30◦C and 80◦C by the
steady-state approximation. In the case of platinum on
Na-mordenite, the reaction between gaseous hydrogen and
tritiated water vapor was almost expressed as first-order
reaction concerning tritiated water vapor concentration.
