Adsorption sites in zeolites A and X probed by competitive adsorption of H(sub 2) with N(sub 2) or O(sub 2): Implications for N(sub 2)/O(sub 2) separation

摘要

The authors determine details of the adsorption of O(sub 2) or N(sub 2) in Li(sup +) exchanged zeolites by way of their effect on coadsorbed H(sub 2) molecules using inelastic neutron scattering (INS) techniques. The results clearly show, for example, the absence of type III cations in Li-A and the expected stronger binding of N(sub 2) (compared with O(sub 2)) and thereby provide insight into the relative efficacy of Li-X for O(sub 2)/N(sub 2) separation.
