摘要/Abstract

摘要： The separation of hydrogen and deuterium by cryogenic adsorption was conducted, using the molecular sieve 5A as adsorbent, helium as the carrier gas in a fixed column. The breakthrough curves of hydrogen, deuterium and the mixture of two components in helium carrier gas were measured, a separation factor, approximately 2, for the hydrogen-deuterium binary mixture was obtained. The equilibrium model was built for simulation of the con-centration distribution for single hydrogen, deuterium and their mixture with helium carrier in the fixed column, and the simulation compared well with the experimental results.
