Abstract

Included are a nano-carbon material production unit (15) for producing a nano-carbon material using a fluidized catalyst (12) formed by granulating a carrier supporting an active component, an acid treatment unit (21) for dissolving and separating a catalyst by an acid solution by feeding a catalyst-containing nano-carbon material (14) into the acid solution, and a pH adjustment unit (23), which is an anti-agglomeration treatment unit, provided on a downstream side of the acid treatment unit (21), for performing an anti-agglomeration treatment to prevent agglomeration among nano-carbons due to repulsion caused by dissociation among oxygen-containing functional groups added to the nano-carbon material.

Description

technical field [0001] The present invention relates to a nanocarbon material production device and a nanocarbon production method that increase the yield of an effective nanocarbon material. Background technique [0002] A carbon nanotube is a tubular carbon polyhedron having a structure in which graphite sheets are closed in a cylindrical shape. The carbon nanotube includes: a multilayer nanotube with a multi-layer structure in which graphite sheets are closed into a cylinder, and a single-layer nanotube with a single-layer structure in which graphite sheets are closed into a cylinder. [0003] The multilayered nanotubes were discovered by Iijima in 1991. That is, it was found that multilayered nanotubes exist in a carbon block deposited on the cathode of the arc discharge method (Non-Patent Document 1). Then, research on multilayer nanotubes has been actively carried out, and in recent years it has been possible to synthesize multilayer nanotubes in large quantities. ...
