Abstract—The effect of the rank of coal (C^daf = 80–95.2%) on the yield and characteristics of activated carbons
prepared under the conditions of alkaline activation (800C, 1 h, Ar) at KOH/coal ratios of 1 g/g was studied.
Under these conditions, the ability of coals to form porous materials decreased in the metamorphic series. Grade
D coal (C^daf = 80%) exhibited a maximum activation ability to form a material with S_BET = 1560 m²/g, V = 0.71
cm³/g, and V_mi = 0.51 cm³/g. A minimum activation ability was found in anthracite (C^daf = 95.2%), which forms
activated carbon with poorly developed porosity (S_BET = 306 m²/g, V = 0.15 cm³/g, and V_mi = 0.11 cm³/g).
