In the paper activated carbons (AC) from three lignocellulosic materials: walnut shells (Juglans regia), pistachio shells (Pistacia vera) and peanut shells (Arachis hypogaea) were obtained. The following physicochemical properties of ACs were examined: content of oxygen surface functional groups by the Boehm method, porous structure by nitrogen sorption at -196oC and thermal resistance by thermogravimetric method. The activated carbons, formed during the KOH activation process, showed an acidic character. However, the use of sodium hydroxide as an activator, promoted the formation of alkaline groups. All activated carbons had a strongly developed surface area, above 1700 m2/g, and a high total pore volume. The largest SBET values had ACs from walnut shells, then from peanut shells and the smallest values had pistachio shells (for both activators). Most of obtained ACs were mesoporous.
