heal.abstract	Mixtures of novolac resin and olive stone biomass ( 20 80 wt./wt.) were cured, pyrolyzed up to 800 °C (material C2) and 1000 °C (C3) and activated with steam (C4). 100% olive stone biomass was also pyrolyzed up to 1000 °C (C1). The pore structure of these materials, along with a commercial activated carbon for comparison purposes, was determined by mercury porosimetry and vapour sorption of pentane, cyclohexane and toluene as well as by sorption of methylene blue dye from its aqueous solution. C1 was found to contain mainly mesopores and only a few micropores; this is the reason it adsorbed methylene blue but did not practically adsorb from the vapour phase. C2, C3 and C4 contained more micropores (C2 < C3 < C4) but they also contained mesopores, and as a consequence they had the ability to adsorb from both the vapour and the liquid phase (aqueous solution of methylene blue). The activated material C4 shows better pore characteristics than the commercial product C5. These results show that the properties of the pyrolyzed composite material are superior to those of the pyrolyzed biomass. It is thus possible to obtain activated carbons with the pore structure and sorption properties desired for the application for which they are destined. © 1995.	en
