A method of producing advanced carbon materials can include providing coal to a processing facility, beneficiating the coal to remove impurities from the coal, processing the beneficiated coal to produce a pitch, and treating the pitch to produce an advanced carbon material such as carbon fibers, carbon nanotubes, graphene, resins, polymers, biomaterials, or other carbon materials.

The proposed method relates to the processing of carbon-containing raw material and may be used to obtain products containing amorphous silica and amorphous carbon of varying degrees of purity. The technical result consists in simplifying the production of a product containing amorphous silica and increasing the yield efficiency for such a product by decreasing the temperature to which the carbon-containing raw material is exposed. The method of producing a product containing amorphous silica and amorphous carbon includes the steps in which a carbon-containing raw material is dried at a temperature of 150-200° C. and the dried raw material is subjected to heat treatment at a temperature of 400-600° C., wherein the heat treatment is performed in the presence of an activator made of a readily fusible alloy. A device for carrying out the method is also proposed.
