D{sub 2} and DT gas purification by cryosorption on 5 Angstrom molecular sieve

Conference:

Abstract

Purification of deuterium and deuterium-tritium gas has been performed by cryosorption of impurities on 5 A molecular sieve as adsorbent. This process is efficient for most of the impurities (nitrogen, methane, oxygen, carbon oxides, argon, water) except helium. In closed loop operations, their residual levels can be better than 10 vpm during at least 5 hours if the trap temperature is sufficiently low (< 93 K). At low temperature, cryosorption of D{sub 2} and DT gas is significant. Nevertheless, their recovery can be easily achieved by heating up the adsorbent.
