Adsorption sites in zeolites A and X probed by competitive adsorption of H2 with N2 or O2: implications for N2/O2 separation.

摘要

We determine details of the adsorption of O(sub 2) or N(sub 2) in Na(sup +) and Li(sup +) exchanged zeolites by way of their effect on coadsorbed H(sub 2) molecules using inelastic neutron scattering (INS) techniques. Adsorption site occupancies are deduced with the aid of MC simulations. The expected stronger binding of N(sub 2) (compared with O(sub 2)) in LiX is evident in coadsorption spectra of N(sub 2) or O(sub 2) with H(sub 2).
