Beschreibung
Zusammenfassung:The present invention relates to a producing method of carbon nanofibers, comprising causing carbon nanofibers to grow on surfaces of particles, the particles having adhered thereto a catalyst component; recovering the particles with grown carbon nanofibers; separating the carbon nanofibers from the surfaces of the particles by a physical process or a chemical process, and recovering the carbon nanofibers, wherein causing the carbon nanofibers to grow is performed by a fluidizing layer reaction process in which the particles are utilized as fluidizing material in a slow fluidizing state, and the particles are violently stirred after reaction termination to separate carbon nanofibers by collision among the particles, and the carbon nanofibers are recovered.
