Chars, prepared by pyrolysis of prune pits at I or lS"C/min to 500, 700 or 9OO"C, were subsequently gasified by CO, at 900Β°C. Pyrolysis conditions did not significantly affect the porosity developed for a given mass loss due specifically to gasification reactions, i.e. excluding additional pyrolytic

A set of samples, including active carbon and ASC-whetlerites, both in their original form and after extraction, all with an identical carbonaceous skeleton, was investigated to specify the porous structure and the deposition of the impregnant. Mercury porosimetry and adsorption of nitrogen and carb
## Abstract In this article, activated carbon aerogels (ACAs) were prepared by CO~2~ activation. Their pore structures were investigated by N~2~ adsorptionβdesorption analysis. ACAs have excellent microporosity (e.g. 0.36 cm^3^/g) and mesoporosity (e.g. 1.72 cm^3^/g). Adsorption characteristics of
