Carbon molecular sieve (CMS) membrane surpasses the upper-bound trade-off and plasticization phenomenon of polymer membrane. Recently, supported CMS membranes have been investigated to provide both high performance and mechanical strength. Herein, we have investigated the supported CMS hollow fiber membranes on low-cost alumina hollow fiber. To prepare the thin and uniform layers, the dip-coating parameters for intermediate and polymeric layers were varied in terms of the withdrawal rate and solution viscosity, respectively. Then, in order to confirm its feasibility in real industry, mixture gas was permeated through prepared CMS membranes. Moreover, the property of long-term stability was characterized in harsh conditions and further modified.
