METHOD FOR PRODUCING GRANULE OF CARBON HAVING DIFFERENT BULK DENSITY AND GRANULE OF CARBON OBTAINED BY THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a granule of carbon which enables high-volume production of a granule of carbon having a high added value and different bulk densities at low cost, in a step of uniformly mixing and granulating CB powder and CNT powder having greatly different bulk densities in a short period of time, facilitates control of a particle diameter, has less scattering of CNT and is excellent in safety of a manufacturing site, and has different bulk densities.;CONSTITUTION: A method for producing a granule of carbon includes: a CNT dispersion step of dispersing CNT having a particle diameter of 100 nm or less in water; a granulation step of mixing CNT dispersion obtained by the CNT dispersion step with CB powder in a disperser and granulating the mixed substance; and a drying step of drying a granulate of carbon obtained in the granulation step.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
