Patent ID: 6878360

Claim:
An apparatus for production of carbon fibrous materials, comprising: a reactor means including a furnace of tubular reactor having a reaction zone for production of the carbon fibrous materials by thermal decomposition of a gaseous carbon source and a metal catalyst source, and a feedstock-supplying means for supplying the carbon source and the metal catalyst source to the furnace of tubular reactor; a discharging means including a discharge pipe having a first opening for charging at least one of the carbon fibrous materials and the carbon source/metal catalyst source and a second opening for discharging the carbon fibrous materials to an outside, the discharge pipe positioned at least partially within the furnace of tubular reactor, and the discharging means being positioned so as to have the first opening of the discharge pipe face in close proximity to the reaction zone; and a guide gas-supplying means for supplying a guide gas in such a manner that the guide gas flows countercurrent to a gas in the discharge pipe and then through the inside of the discharge pipe.
