Boehmite-phenolic resin carbon molecular sieve membranes-Permeation and adsorption studies

- Adsorption and permeation studies were carried out in composite carbon membranes.
- The membranes exhibited mostly kinetic selectivity for O2/N2 and C3H6/C3H8.
- Ideal C3H6/C3H8 selectivities were up to 19 and real selectivites up to 13.6.
- Permeance decreased after exposure to air but could be restored with N2 treatment.
