Verification of hydrogen isotope separation by pressure swing adsorption process: Successive volume reduction of isotopic gas mixture using SZ-5A column

Breakthrough curves of non-trace H2–D2 mixture replacement adsorption with SZ-13X packed column at 77.4K

“…In previous works [1][2][3][4][5][6][7][8], they clarified dynamic behaviors of trace one in H 2 -D 2 (99:1) mixtures in zeolite packed columns from the breakthrough curve analysis. The tracer curves can be analytical because assumptions are acceptable of ignoring the fluid outflow-rate change with breakthrough concentration variation and the change of isotope separation factor in binary component adsorption equilibrium depending on concentration.…”
