METHOD OF PRODUCTION OF THE NANOCARBONIC MATERIAL Russian patent published in 2007 - IPC C01B31/02 B82B3/00 

FIELD: chemical industry; methods of production of the nanocarbonic materials.

SUBSTANCE: the invention is intended for chemical industry and may be used at production of the heterogeneous catalysts for synthesis of the isoalkanes from the methane, the natural gas, the synthesis gas, the catalytic oxidation of carbon monoxide. The source raw is schungite, which is sequentially treated at heating with the melted alkali at the temperature of no more than 500°C; and in the mode of boiling it is treated with the concentrated inorganic acid, in the capacity of which they use НСl or HF; and with the strong oxidant from the row including HClO₄ and ВаО₂ in the mode of boiling treatment at the temperature of up to 150°С within no more than 2 h. After treatment with each of these reactants the formed intermediate product is flushed and dried. Then conduct the thermal treatment with the high-temperature gaseous oxidation in the oxygen or air medium in the high-temperature furnace at the temperature of 700-1200°С with production of the target product - the nanocarbonic material. The invention allows to produce the nanocarbonic material containing up to 90 mass % of the nanotubes and others nanocarbonic forms, and up to 70 mass % of the open nanocarbonic forms; and also one time to treat of no less than 100 kg of schungite in one apparatus with the volume of no more than 70 l. At that the output of the nanocarbonic material is up to 20 mass % from the initial mass of mass of schungite.

EFFECT: the invention allows to produce up to 20 mass percent of the nanocarbonic material from the initial mass of schungite.
