    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： A method for producing carbon fiber including the following processes: a process for obtaining fine carbon fiber by thermally decomposing an organic compound in a furnace by use of a catalyst; a process for separating a reaction exhaust gas contained in the carbon fiber; a process for continuously subjecting the carbon fiber to thermal treatment in a non-oxidative atmosphere; and a process for incinerating a thermal treatment exhaust gas generated in the thermal treatment and/or the reaction exhaust gas. The method for separating a reaction exhaust gas from carbon fiber is characterized in that a packed carbon fiber layer is formed, an inert gas is caused to flow through the layer, and the layer is compressed. Combustion of the reaction exhaust gas and combustion of the exhaust gas generated from the subsequent thermal treatment is achieved through employment of a pilot burner holding flame at all times in a vertical incinerator.

    摘要： An object of the present invention is to provide a method and apparatus for heat-treating carbon fiber, in which impairment of a furnace caused by solidification of a transition metal impurity serving as a catalyst raw material is prevented, and the amount of the metal, such as Fe, Co, or Ni, contained in the carbon fiber is reduced. In the present invention, a vaporized metal impurity is contained in an inert gas that is passed through a furnace, and the gas is discharged from a high-temperature section of the furnace. The impurity contained in the gas discharged from the furnace is cooled to solidify, and then recovered. The resultant gas is recycled as an inert gas in the furnace.
