Activated carbon monoliths with different
surface characteristics were prepared by impregnating
oil palm stone with diluted aqueous CaCl2 solutions (with
concentrations between 2 and 7% w/v) without binders.
The solids were characterized by determination of
nitrogen adsorption isotherms at 77 K and carbon dioxide
adsorption isotherms at 273 K using volumetric adsorption
equipment. Surface area and micropore volume values
were calculated from the nitrogen isotherms using the
BET and DR models, respectively, obtaining solids with
low percentages of mesoporosity. Immersion enthalpies
of the activated carbon monoliths were determined in
benzene, with values between -173 and -104 J g-1, and
water, with values between 61 and 30 J g-1, indicating that
the monoliths have a hydrophobic character.
