Summary: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. L'invention concerne des membranes à fibres creuses ("CMS") de type tamis moléculaire carboné multicouches asymétriques et des procédés pour préparer les membranes. Les procédés comprennent l'extrusion simultanée d'un dopant de noyau contenant un polymère et des nanoparticules appropriées, d'un dopant d'enveloppe, et d'un fluide d'âme, suivie par une pyrolyse de la fibre extrudée.
