The mechanism of formation of a porous active carbon framework is considered, and the properties of the solid thermolysis products of brown coal (Aleksandriisk deposit, Ukraine) with potassium hydroxide are studied. The yields of the solid thermolysis products and potassium humates, the rate of the interaction of the solid thermolysis products with KOH at 700-900{sup o}C, the specific surface areas, the adsorption capacities for methylene blue and iodine, and the specific activities of surface areas are determined under variation of the KOH/coal ratio KOH < 18 mol/kg and temperature (110-900{sup o}C).
