FIELD: chemistry.SUBSTANCE: invention relates to methods of producing activated carbon. The carbon precursor material in form of fibre with diameter of 7-20 mcm is coated with a phosphorus-based chemical solution and activated. Activated carbon can also be formed by coating an immature carbon precursor with a chemical solution which chemically reacts with carbon, followed by carbonisation of the obtained material and physical activation of the material during at least part of the carbonisation operation. In another version, activated carbon can be formed by coating carbon or a carbon precursor with iron and nickel nanoparticles and carbonisation. If the carbon is a carbon precursor, subsequent catalytic activation in air and inert gas, and physical activation in steam or carbon dioxide gas is carried out. If the carbon is not a carbon precursor, catalytic activation and physical activation of the chemically pre-activated carbon is carried out after coating with nanoparticles.EFFECT: invention enables to obtain activated carbon, having controlled mesoporosity.15 cl, 18 dwg, 6 tbl, 11 ex |
