METHOD AND APPARATUS FOR PRODUCING FINE CARBON MATERIAL

摘要

An apparatus for producing carbon nanotube which comprises a reacting furnace 10 which is vertically installed for forming a fine carbon material by the chemical vapor deposition method, a carrier supplying device 14 which is connected to the reacting furnace at its upper end portion for introducing carrier particles having a catalyst carried thereon into the reacting furnace, a reacting gas supplying device 17 for supplying a reacting gas containing a hydrocarbon into the reacting furnace, a carrier recovery device 21 which is connected to the reacting furnace at its lower end portion for discharging the carrier particles after the reaction out of the reacting furnace, and a reacted gas recovery device 27 which is connected to the reacting furnace at its upper end portion for discharging the gas having been reacted in the reacting furnace out of the furnace and a method for producing a carbon nanotube using the apparatus. The apparatus can be used for producing a carbon nanotube having a fine fiber diameter and a sharp distribution of the diameter on a large scale with stability.
