Chemical composition of lignocellulose materials and porous structure of activated carbons.Chemical and elemental compositions of selected lignocellulose materials were determined and next a series of activated carbons was produced from these materials under strictlyrepeatable conditions. The chemical activation method (900 o C) using KOH (4:1) was applied for the development ofthe porous structure. Prior to activation all raw materials were subjected to pyrolysis at 700 o C using a slight temperature increase rate (3 o C/min). Produced activated carbons had varied porous structure parameters and considerable BET surface areas ranging from 2026 to 2884 m 2 /g. It was shown that the type of the applied precursor has a significant effect on the development of the porous structure.
