Adsorption properties and structure of some active carbons

Gas chromatography has been used to determine the initial low-coverage heats of adsorption of C 2 -C 6 hydrocarbons and their derivatives on active carbon and graphitized carbon black. The porous structure of the active carbon has been determined from the adsorption isotherms of benzene measured at 25°C by a vacuum static method. The isotherms have been analyzed with the help of the BET and Dubinin-Radushkevich theories. The adsorbents investigated were classified as type 1 adsorbents according to Kiselev's classification.
