RELATION BETWEEN IMMERSION ENTHALPY OF ACTIVATED CARBON MONOLITHS AND TEXTURAL PARAMETERS

RELATION BETWEEN IMMERSION ENTHALPY OF ACTIVATED CARBON MONOLITHS AND TEXTURAL PARAMETERS. In this study, Disc and honeycomb-shaped activated carbon monoliths were obtained using as a precursor coconut shell, without the use of any binder. Textural characterization was performed by adsorption of N-2 at 77 K and immersion calorimetry into benzene. The experimental results showed that the activation with zinc chloride produces a wide development of micropores, yielding micropore volumes between 0,38 and 0,79 cm(3) g(-1), apparent BET surface area between 725 and 1523 m(2) g(-1) and immersion enthalpy between 73,5 and 164,2 J g(-1). Were made comparisons between textural parameters and energy characteristics.
