✦ Synopsis

A feasibility study was conducted to explore the potential application of carbon molecular sieve membranes (CMSMs) in biofuel separation through pervaporation. ''Defect-free'' carbon/ceramic composite membranes were prepared as the separation barrier for the dehydration of ethanol. The supported CMSM carbonized at 650 Β°C showed a great total flux of 4 kg/m 2 h with a reasonably high separation factor of 50 at a feed temperature of 60 Β°C and did not swell in high temperature operations. These carbon membranes demonstrate outstanding separation performance and offer a viable alternative to current membranes for the separation and purification of biofuels.

Carbon molecular sieving (CMS) membranes have been found to have exceptional gas separation properties with high-purity feeds. The basic nature of the carbon itself, however, makes these membranes vulnerable to compounds typically found in industrial process streams. Because of their organophilic na
