Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
We claim: 1. A carbon molecular sieve prepared by a method comprising: pyrolyzing a polymer membrane in a first heat treatment in a first oxygen environment comprising less than 5 ppm oxygen; and subjecting the pyrolyzed polymer membrane to a second heat treatment in a second oxygen environment; wherein the second heat treatment occurs at a temperature above the first heat treatment; and wherein the second oxygen environment has a higher concentration of oxygen than the firs…
