  • CARBON NANOTUBE PRODUCTION DEVICE AND PRODUCTION METHOD
    Publication number: 20220274836
    Abstract: Provided are a carbon nanotube production device and production method capable of realizing high-temperature heating of a catalyst raw material in a floating catalyst chemical vapor deposition (FCCVD) method, and improving the quality and yield of carbon nanotubes synthesized. A carbon nanotube production device 1 includes a synthesis furnace 2 for synthesizing carbon nanotubes; a catalyst raw material supplying nozzle 3 for supplying a catalyst raw material used to synthesize carbon nanotubes to the synthesis furnace 2; and a nozzle temperature adjusting unit 6 capable of setting a temperature of an inner portion 4 of the catalyst raw material supplying nozzle 3 higher than a temperature of a reaction field 5 of the synthesis furnace 2.
