Claims
- 1. A process for the separation of nitrogen from a nitrogen-containing gas mixture comprising contacting the mixture with a composition comprising a zeolite having a mole ratio of about 20 or greater of an oxide selected from the group consisting of silicon oxide, germanium oxide and mixtures thereof to an oxide selected from aluminum oxide, gallium oxide, iron oxide, titanium oxide, indium oxide, vanadium oxide and mixtures thereof, and having, after calcination, the X-ray diffraction lines of Table I.
- 2. The process of claim 1 wherein the gas mixture contains methane.
