METHOD OF OBTAINING POROUS CARBON MATERIAL WITH BIMODAL DISTRIBUTION OF PORES Russian patent published in 2014 - IPC B01J20/20 C01B31/08 

FIELD: chemistry.

SUBSTANCE: process of obtaining granulated porous carbon material consists of two stages. At the first stage soot is mixed with petroleum pitch and solvent, after which obtained mixture is granulated, granules are stabilised in gas medium at temperature not higher than 250°C, subjected to carbonisation at 600-1200°C and cooled. Product, obtained at first stage, possesses narrow distribution of pores. At the second stage product, obtained at first stage, is crushed to particle size smaller than 1 mm, mixed with petroleum pitch and solvent, mixture is granulated. Obtained granules are subjected to stabilisation and carbonisation under the same conditions as at the first stage.

EFFECT: providing possibility of obtaining porous carbon material, characterized by bimodal distribution of pores and low soot content.
