Abstract

This disclosure is directed to uses for a new crystalline molecular sieve designated SSZ-100. SSZ-100 is synthesized using a cationic nitrogen-containing organic compound having the following structure:

First claim

The invention claimed is:

1. In a process for separating gases using a membrane containing a molecular sieve, the improvement comprising using as the molecular sieve a molecular sieve having a mole ratio of at least 10 of (1) at least one oxide of at least one tetravalent element to (2) one or more oxides selected from the group consisting of trivalent elements, pentavalent elements, and mixtures thereof, and having, in its calcined form, an X-ray diffraction substantially as shown in the following Table:
