dc.description.abstractIn this work, carbon molecular sieve (CMS) membranes were successfully synthesis from polyetherimide. Porous carbon disks (diameter 20mm, thickness 2.5mm) as support were prepared first by agglomeration of fine powdered carbon black with phenolic resin. The polyetherimide solution was coated onto the support and then pyrolyzed at various temperatures and times to form molecular sieve layer. Response surface methodology (RSM) was used to evaluate the contribution of the preparation parameters onto responses which were permselectivity of H2/N2, CO2/CH4 and O2/N2. The optimum preparation conditions for the CMS membrane were obtained at 722°C, 3 hours and 7.92 wt% respectively for pyrolysis temperature, pyrolysis time and polymer concentration which gave result of 6.70, 4.32 and 2.04 for the H2/N2, CO2/CH4 and O2/N2 permselectivity, respectively. The characterization of CMS membrane reveals the existing of microporous carbon film with various functional groups exists on the surface. The BET surface area, micropore volume and average pore diameter of CMS membrane were 342.01 m2/g, 0.19 cm3/g and 0.36 nm, respectively. The gas permeation was found to increase with increase in permeation temperature and feed pressure.en_US
