APPARATUS AND METHOD FOR PRODUCING FINE CARBON FIBER BY VAPOR GROWTH, ANTISTICKING APPARATUS FOR FINE CARBON FIBER BY VAPOR GROWTH, AND FINE CARBON FIBER BY VAPOR GROWTH

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and a method for producing fine carbon fiber by vapor growth which can continuously produce fine carbon fiber by vapor growth for a long term without causing clogging accidents in the core tube of a furnace, to provide an antisticking apparatus for fine carbon fiber by vapor growth and to provide fine carbon fiber by vapor growth which is produced by the same producing apparatus. SOLUTION: The apparatus for producing fine carbon fiber by vapor growth is constituted by inserting and installing a discharge tube within the core tube of a furnace in such a way that the opening of the discharge tube is placed facing an opening at the tip of a raw material gas-feeding nozzle located at the one end of the core tube of a furnace. The method for producing the fine carbon fiber by vapor growth, especially carbon nanofiber and/or carbon nanotubes is to use the above apparatus. The antisticking apparatus for fine carbon fiber by vapor growth has a device for preventing the adhesion of carbonaceous matter such as fine carbon fiber by vapor growth in the inside wall of the core tube of a furnace. The fine carbon fiber by vapor growth is produced by using the above producing apparatus.
