Abstract

Novel Cd-exchanged rho compositions and compositions of zeolite rho encapsulated with hydrogen made therefrom are disclosed. The Cd-exchanged zeolite rho compositions are useful in separating and selectively removing hydrogen from hydrogen-containing process streams and storing the separated hydrogen therein. Encapsulation of hydrogen can be accomplished in large amounts even at pressures of 1 atmosphere.
