FIELD: carbon materials. ^ SUBSTANCE: preparation of carbon material from organic raw material comprises carbonization of raw material in non-oxidative medium and activation by oxygen-containing agents at 750-900°C, said raw material being sapropel with content of organic substance 55-98%. Raw material is preliminarily cooled to 0-(-50)°C and carbonization is carried out at 300-700°C until summary pore volume 0.3-2.5 cm3/g and average macropore radius 100 to 5000 nm are obtained at following size distribution of pore radius: 60-80% above 100 nm, 15-30% 2-100 nm, and 1-10% below 2 nm based on total pore volume. Carbonized product is activated to give following size distribution: 50-75% above 100 nm, 20-40% 2-100 nm, and 1-15% below 2 nm. Material having mainly macroporous structure can be used as carrier in preparation of various-type catalysts and as matrix in preparation of deposited sorbents. ^ EFFECT: optimized preparation process conditions. ^ 1 tbl, 18 ex |
