Multi-Component Adsorption Behavior of Hydrogen Isotopes on Zeolite 5A and 13X at 77.4 K
- Kyushu University (Japan)
Equilibrium isotherms for the adsorption of H{sub 2}, HD, HT, D{sub 2}, DT and T{sub 2} on synthetic zeolite type 5A or 13X at 77.4 K are estimated by using a theoretical formula, where the isotopic difference in adsorption depends on the zero-point energy difference between hydrogen isotopes. The formula agrees with the experimental isotherms for H{sub 2} and D{sub 2} on the zeolites. Adsorption of H{sub 2}-D{sub 2} and H{sub 2}-HD-D{sub 2} mixtures on the same adsorbents is experimentally examined. The experiments are performed using a volumetric apparatus and a quadra-pole-type mass spectrograph. The experimental adsorption behavior of H{sub 2}, D{sub 2} and HD shows agreement of separation factors with results calculated according to the ideal adsorbed solution theory describing multi-component behavior, where the equilibrium isotherms estimated for H{sub 2}, HD and D{sub 2} are used. Based on the theoretical adsorption model, the multi-component behavior of HT, DT and T{sub 2} is predicted here.
