PROCESS FOR PREPARING AGGREGATES OF CARBON NANOTUBES

摘要

Provided is a preparation method of carbon nanotube aggregates with improved dispersion characteristics while being capable of having a fluidized-bed reaction. The preparation method comprises the steps of: forming carriers by heat-treating the support catalyst including metal hydroxide having a layered structure; forming a supported catalyst by supporting catalytic metal or catalytic metal precursor in the carriers; and forming carbon nanotube aggregates by contacting the support catalyst and a carbon-containing compound in the heating zone.
