CARBON NANOTUBE SYNTHESIS METHOD Russian patent published in 2010 - IPC B82B3/00 D01F9/127 C01B31/02 

FIELD: chemistry.

SUBSTANCE: invention relates to technology of producing fibrous carbon materials through pyrolysis of aromatic and non-aromatic hydrocarbons. A catalyst 9 is deposited on the top surface of a container 8. After sealing the reactor, inert gas is blown inside and heating elements 5 and the disc 6 rotary actuator 7 are switched on. Carbon-bearing gas is fed into the cavity between the cap 10 and the container 8 and the catalyst 9 is heated. Heating is then stopped and a forced cooling system is switched on. After lowering temperature in the reactor, the disc 6 rotary actuator 7 is switched off, the reactor is opened and the container 8 with nanotubes is removed.

EFFECT: invention enables to obtain multilayer carbon nanotubes with diametre of 15-50 nm.
