Abstract
The various embodiments of the disclosure relate generally to carbon molecular sieve membranes (CMSM) and their associated fabrication processes for the separation of nitrogen/methane gas mixtures, and more particularly to CMSM that maintain high nitrogen-methane selectivity and high gas permeabilities. Methods for removing nitrogen from a nitrogen methane mixture gas via the use of the CMS membranes and gas enrichment devices using the same are also disclosed.
