Adsorption isotherms of light normal alkanes on three different activated carbons were measured and compared with benzene adsorption isotherms on these carbons. Analysis by means of the Dubinin-Radushkevich equation revealed the utility of the adsorption isotherms of ethane, propane, and n-butane for describing the microporosity of activated carbons. On the basis of these studies, the authors recommend that n-butane be used as a reference adsorbate for characterization of microporous activated carbons.
