Title: A CARBON MOLECULAR SIEVE MEMBRANE, METHOD OF PREPARATION AND USES THEREOF
Abstract:
The present disclosure relates to a novel carbon molecular sieve membranes - CMSM. More particularly, the disclosure relates to the polymeric precursor and carbonization conditions needed for producing a high-selective, age-free CMSM. More specifically, the present subject-matter discloses a process for obtaining from a cellophane film and in a single carbonization step. The carbon molecular sieve membrane obtainable be the process describe displays no pore blockage in the presence of water vapor and displaying very high ideal permselectivities and permeabilities for industrially relevant gas mixtures.
