The influence of thermal pretreatment of aspen wood at conditions of pyrolysis and explosive
autohydrolysis on the texture and adsorption properties of porous carbon materials (PCM), obtained
by alkaline activation of modified samples, was studied. Preliminary pyrolysis of wood at 300-400 °С
promotes the development of porous structure of PCM in the higher degree as compared to explosive
autohydrolysis at 170-200 °С. At optimal conditions of pyrolysis and alkaline activation processes it is
possible to obtain PCM with specific surface area about 3000 m
