Keywords Nanoporous carbon materials, Surface area, Thermochemical activation.

The structural-adsorption characteristics of nanoporous carbon materials (NСMs), obtained by thermochemical activation of vegetable raw materials by orthophosphoric acid with different mass ratio, are investigated in the article using the method of low temperature nitrogen sorption and scanning electron microscopy. Calculations of the specific surface area and pore size distribution allowed to determine the optimal parameters of the mass ratio of the activator and the raw materials, in which the obtained material has the highest parameters of the porous structure. The optimum conditions for NCMs obtaining are established, which can be used as electrodes of electric energy storage devices.
