Abstract
Provided are methods of preparing carbon molecular sieve (CMS) hollow fiber membranes derived from polybenzimidazole (PBI) hollow fiber membranes, obtained by contacting a PBI hollow fiber membrane with a cross-linking or acid solution prior to carbonization. CMS hollow fiber membranes obtained by these methods, and methods of using said CMS hollow fiber membranes for fluid separation and purification, are also provided.
