COMPOSITE NANOPARTICLE STABILIZED CORE CARBON MOLECULAR SIEVE HOLLOW FIBER MEMBRANES HAVING IMPROVED PERMEANCE

摘要

Disclosed herein are asymmetric multilayer carbon molecular sieve ("CMS") hollow fiber membranes and processes for preparing the membranes. The processes include simultaneously extruding a core dope containing a polymer and suitable nanoparticles, a sheath dope, and a bore fluid, followed by pyrolysis of the extruded fiber.
