Abstract

Ceramic foam substrates of various porosities were coated with novolak resin, which was then subsequently carbonised and activated to develop a pore structure. The carbon forming the layer was characterised by thermal analysis, TPD and N2, CO2 and hexane vapour adsorption. It was found to be microporous with a high surface area (up to 1400 m2 g−1), which made it a good adsorbent for hexane vapour at ambient temperature. The carbon–ceramic interface was examined using SEM. The coated foams displayed a reduced pressure drop compared to carbon granules and had good dynamic hexane vapour adsorption characteristics. Depending on the foam architecture, hexane breakthrough was delayed for up to 78 min.
