Experiments of Continuous Gas Separation for D2/He Mixed Gas under Room Temperature

Following the experiments on H2/He separation which was reported in the 41st meeting, the experiments on D2/He separation has been performed by using the new method named Continuous Circulation Chromatograph method (C3 method). The D2/He mixed gas were separated into each gas component as well as the H2/He mixed gas with a molecular-sieve as the adsorbent material and Ar as the carrier gas. From the experimental results of both H2/He mixed gas and D2/He mixed gas, it was confirmed that the same result would be obtained on the T2/He mixed gas and the C3 method could be applicable for use in a fuel cycle of the fusion reactor. In addition, the experiments on H2/D2 separation has been attempted. The results showed that the H2/D2 mixed gas could be separated into H2 and D2 with the carrier gas of a small mass such as He.
