DEVICE OF CARBON NANOTUBES GROWTH BY METHOD OF ETHANOL PYROLYSIS Russian patent published in 2009 - IPC C23C16/26 B82B3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to devices for carbon nanotubes production. Device contains reaction furnace with unit for supplying and introducing of ethanol vapours, holder of padding with padding, which has catalytic surface, and heating element. Inside of reaction furnace placed is reaction chamber, which contains separable part, joint with drive of axial movement. Unit of ethanol vapours supply contains evaporating cell with ethanol, joint with ethanol vapours input. Heating element is placed inside reaction chamber in padding zone. Device is supplied with generator of particle flow, placed in reaction chamber, and made in form of at least one conductive net, connected to source of alternating or/and source of continued voltage. At least one conductive net is made of catalytic material. Reaction chamber is made of quartz ceramics. In evaporating cell heater and ethanol temperature measuring instrument are placed. Inlet of ethanol vapours is made of conductive material, and is connected to source of alternating or/and source of continued voltage. Inlet of ethanol vapours is made in form of two pipes, which are coaxially placed one in the other with ability to move relative each other.

EFFECT: increasing nanotubes quality and device reliability.
