Hydrogen isotope separation based on isotopic exchange in palladium bed
- Kyushu Univ., Fukuoka (Japan)
A continuous hydrogen isotope separation system using twin beds of metals or alloys is here proposed. The isotope separation system called a twin-bed periodically counter-current flow (TB-PCCF) is analytically and experimentally investigated. Palladium and LaNi{sub 4.7}Al{sub 0.3} were selected based on experimental data of the isotope separation factor and the isotopic exchange rate. Numerical calculations by a plate model revealed effectiveness of the TB-PCCF method which is composed of an enriching column packed with Pd particles and a stripping column packed with LaNi{sub 4.7}Al{sub 0.3} particles. A preliminary experiment was performed at the condition where absorption and desorption cycles are repeated between room temperature and 473K for Pd and 363K for LaNi{sub 4.7}Al{sub 0.3} at the total reflux, and it showed possibility of the hydrogen isotope separation. 13 refs., 8 figs.
