Received June 5, 2008 Abstract — The composite carbon–carbon membranes (CMS membranes) obtained by polymer modification of a mesoporous carbon substrate through the formation of an activated carbon layer have microporous structures (specific micropore volume 0.11 0.05 cm3/g). The size distribution of micropores shows two distinct peaks at 4.5 to 6.5 and 7.0 to 9.0 Å. The micropores with these widths adsorb well CO2 and 4, respectively.
