A research is done to characterize the microporous structure of outgoing and thermally modified (673 K, 180 min) plant-extracted carbon material. The porous system characteristics are worked out by different methods on low temperature (77K) N2 adsorption-desorption based isotherm. It is stated that thermal modification contributes to the enlargement of specific       surface (from 361 m2/g to 673 m2/g), an increase in total pore volume (from 0,166 cm3/g                    to 0,477 cm3/g) and an increase in micropore volume (from 0,127 cm3/g to 0,173 cm3/g). Most effectively thermal modification  is apt to form nanopores with diameters of 0,75; 1,25 and 4 nm.
