Abstract

Carbon molecular sieve (CMS) membranes intrinsically offer superior separation performance compared to polymer-based analogs. Prior work showed that the CMS membrane performance can be tuned via pyrolysis temperature and atmosphere. A new approach, termed dual temperature secondary oxygen doping (DTSOD) offers a significant improvement beyond simple pyrolysis temperature and atmosphere control. Exceptional gas separation properties were found for CMS membranes produced with DTSOD approach. In addition, these membranes are resistant to some aggressive contaminants at high temperature over 182 oC. The detailed description of protocols for preparation of these advanced membranes and their performance in the aggressive feeds will be described
