<p>The present invention is a composition, a synthesis of the composition and a method of using the composition for selectively adsorptively separating nitrogen from oxygen wherein the composition is a crystalline EMT with a Si/Al ratio less than 2.0 and a lithium cation exchange of at least 80%, preferably including an intergrowth with a crystalline FAU structure, wherein the pure or intergrowth compositions have the chemical formula: (0.20-0.0)M2/nO:(0.80-1.0)Li2O:X2O3:(2.0 to <4.0)SiO2 wherein M = a metal cation other than lithium having a valence of n, and X is selected from the group consisting of aluminum, gallium and boron, preferably aluminum. <IMAGE></p> |
