Carbon Molecular Sieve Membrane (CMSM) Performance Tuning By Dual Temperature Secondary Oxygen Doping (DTSOD)

Abstract

The various embodiments of the disclosure relate generally to carbon molecular sieve membranes (CMSM) and their associated fabrication processes, and more particularly to CMSM that maintain high gas selectivities without losing productivity. Methods for enriching a mixture of gases in one gas via the use of the CMS membranes, and gas enrichment devices using the same, are also disclosed.
