dc.description.abstractThe application of inorganic membrane would minimize the problems suffered by conventional gas separation technologies such as adsorption, chemical process and polymeric membrane. In this work carbon molecular sieve (CMS) membranes were successfully prepared from polyfurfuryl alcohol (PFA). The CMS membrane substrate was prepared first by coating the dope solution of titania sol onto the titania disk and heated from 300 to 600˚C of sintering temperature. On the other hand, the carbon film was formed by dipping the substrate onto PFA solution followed by carbonization between 400 to 600˚C for 1 to 4 hours of thermal soak times. The average pore size and d-spacing were reduced to 4.72Å and 3.67Å, respectively as the carbonization temperature increase up to 600oC. On the other hand, the elemental analysis verified that the carbonization at 600˚C induce 41% and 87% percentage reduction of [H]/[C] and [O]/[C] ratios, respectively. The analysis of variance reveal the carbonization temperature exhibits significant effect on gas permeances and ideal selectivity compared to thermal soak time. The optimum CMS membrane preparation conditions were obtained at 600°C and 4 hours of carbonization temperature and thermal soak time, respectively. The permeation properties of the optimum CMS membrane were 4.95×10-8 mol/m2.s.Pa, 7.74×10-8 mol/m2.s.Pa, 1.82 and 5.31 for O2 permeance, CO2 permeance, O2/N2 ideal selectivity and CO2/CH4 ideal selectivity respectively. The optimum CMS membrane possesses the highest gas permeance and ideal selectivity.en_US
