FIELD: nanotechnology.
SUBSTANCE: invention refers to nanotechnology. Carbon nanotubes are produced. As a carbon-bearing substance antracite, crozzling coal, shungite, coak, charcoal or their mixture is used. The carbon-bearing substance is powdered with the particle size of 150-1,000 nm in mill1. Then the obtained powder is mixed in forehearth 2 with the flow of neutral gas that has a temperature within the range from 275 to 750 K and the pressure within the range from 0.15 to 0.8 MPa. The obtained two-phase mixture passes through nozzles 5. The two-phase flow that was formed after interaction of the colliding currents is separated in separator 7, filtered in filter 8. The carbon nanotubes collected in the collector are classified according to their size and fraction.
EFFECT: reduction of the prime cost with the same high quality of carbon nanotubes.
