Nitrogen isotherms have been determined at 77 K on four active carbons, used as adsorbents in gas masks, before and after n-nonane ~readsorption. The four carbons contain both micro and mesopores. After n-nonane preadsorption, mesoporosity is still observed, together with a, low pressure hysteresis

β¦ Synopsis
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 losses.

## 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
