Abstract

A Spanish bituminous coal was used as raw material to prepare activated carbons both by CO2 and by chemical activation. The activated carbons were characterized by adsorption of N-2 at 77 K, CO2 at 273 K and benzene and cyclohexane at 303 K, as well as by mercury porosimetry andhelium density. The microporosity of the activated carbons was evaluated by the Dubinin-Astakhov equation applied to the adsorption isotherms and the ct-plot method applied to the N-2 adsorption data. All activated carbons studied were essentially microporous. The sample obtained by chemical activation with phosphoric acid had the widest micropores. The micropore volumes of activated carbons with medium to high activation determined by N-2 and CO2 adsorption were quite similar, so both adsorbates measured the same type of micropores. Molecular sieve effects for benzene and cyclohexane were detected in activated carbons with low to medium activation. (C) 1996 Elsevier Science Ltd.
