Title: Carbon Molecular Sieve Membrane Preparation by Economical Coating and Pyrolysis of Porous Polymer Hollow Fibers

Journal Article · · Angewandte Chemie (International Edition)

Abstract Dip coating and pyrolysis processes are used to create multi‐layer asymmetric carbon molecular sieve (CMS) hollow fiber membranes with excellent gas separation properties. Coating of an economical engineered support with a high‐performance polyimide to create precursor fibers with a dense skin layer reduces material cost by 25‐fold compared to monolithic precursors or ceramic supports. CMS permeation results with CO 2 /CH 4 (50:50) mixed gas feed show attractive CO 2 /CH 4 selectivity of 58.8 and CO 2 permeance of 310 GPU at 35 °C.
