    摘要： A fine carbon fiber having an outer diameter of about 1 to about 80 nm and an aspect ratio of 10 to 30,000, comprising a hollow center portion and a multi-layer sheath structure of a plurality of carbon layers, the layers forming annual rings, wherein the sheath-forming carbon layers form an incomplete sheath, i.e., the carbon layers are partially broken or disrupted in a longitudinal direction, and the outer diameter of the carbon fiber and/or the diameter of the hollow center portion are not uniform in a longitudinal direction. The carbon fiber is obtained by instantaneously reacting a carrier gas at a high temperature and an organic compound gas kept at a temperature below the decomposition temperature of the transition metal compound and has a conductivity equivalent to that of a conventional vapor phase method and is useful as a filler material in resins, rubbers, paints and the like.

    摘要： The objective of the present invention is to provide a process of producing single-walled carbon nanotubes, capable of producing single-walled carbon nanotubes with high purity. A process of producing single-walled carbon nanotubes according to the present invention includes feeding a feedstock including a hydrocarbon source, a metallocene, and a sulfur compound in a state of mist to a feeding zone where hydrogen gas flows at a linear velocity of 1-50 m/second wherein the amount of the hydrocarbon source is 0.01-0.2% by mass and the amount of the metallocene is 0.001-0.2% by mass based on the total amount of the hydrogen gas and the feedstock, and the amount by mass of the sulfur compound is ⅛-4 times as much as that of the metallocene; and making the hydrogen gas and the fed feedstock flow through a reaction zone with a temperature of 800-1000° C.
