Beschreibung
Zusammenfassung:	This invention provides an apparatus for production of vapor-phase growth carbon fibers , which can continuously produce these carbon fibers for a long time without blocking the furnace of tubular reactor of the apparatus, a process for production of the carbon fibers by means of the apparatus, a device for preventing the deposition of the carbon fibers on the inside of the furnace of tubular reactor, and the vapor-phase growth carbon fibers produced in the apparatus. The vapor-phase growth carbon fibers include carbon nanofibers and/or carbon nanotubes. The apparatus is comprised of a furnace of tubular reactor, at an end of which a feedstock-supplying nozzle is provided, and a discharge pipe inserted in the furnace of tubular reactor, the top end of which faces the opening of the nozzle and the bottom end discharges the carbon fibers.
