Abstract

Disclosed is an apparatus (1) for producing a nanocarbon material, which is characterized by comprising: a reaction tube (2) wherein a starting material gas and a carrier gas are supplied and a nanocarbon material is grown; a connection tube (4), which is connected to the reaction tube (2), and through which an aerosol-like mixture of the nanocarbon material and the carrier gas passes; and a collection tube (3), which is connected to the connection tube (4) and collects the nanocarbon material from the mixture. The apparatus (1) for producing a nanocarbon material is also characterized in that the collection tube (3) comprises a discharge section (32) that is located above a connection part (33), at which the collection tube (3) is connected to the connection tube (4), and discharges the carrier gas contained in the mixture to the outside, and a trapping section (31) that is located below the connection part (33), at which the collection tube (3) is connected to the connection tube (4), and traps the nanocarbon material that is separated from the mixture by means of gravitational sedimentation.

Description

Technical field [0001] The invention relates to a nano carbon material manufacturing device and a method for manufacturing a nano carbon material using the nano carbon material manufacturing device. Background technique [0002] As a technique in this field, for example, there is a carbon nanotube production apparatus described in Patent Document 1. In this device, by supplying a raw material gas including a carbon source and a catalyst and a carrier gas from the upper part of the reaction tube, the growth and synthesis of carbon nanotubes (the so-called gas-phase flow method) is realized during the descending process of the reaction tube. In addition, in the manufacturing apparatus of the nanocarbon material described in Patent Document 2, the carbon raw material and the flowing gas are supplied to the catalyst carrier in the reaction section to grow the nanocarbon material.
