摘要： The subject invention provides a stable mass production method of carbon nano structure at low cost immune to variation of particle diameter of the catalyst microparticle in the catalyst material. The subject invention also provides a production device used for the method, and a new carbon nano structure having a conformation suitable for the mass production. The production method of carbon nano structure comprising fluidizing a material gas and catalyst microparticles in the reactor so that the material gas and the catalyst microparticles are brought into contact with each other, wherein said catalyst microparticles are suspended by the instantaneous spraying of the high-pressure gas, and then the suspension effect of the catalyst microparticles is stopped so that the catalyst microparticles naturally fall. The particle diameter of the catalyst microparticles is thus selected. With this arrangement, only the selected catalyst microparticles with the desired diameter are supplied to the reactor. Since this arrangement is immune to influence of variation in particle diameter of catalyst microparticles contained in the catalyst material, it achieves stable mass production of carbon nano structure at low cost.

摘要： A method for synthesizing carbon nanocoils with high efficiency, by determining the structure of carbon nuclei that have been attached to the ends of carbon nanocoils and thus specifying a true catalyst for synthesizing carbon nanocoils is implemented. The catalyst for synthesizing carbon nanocoils according to the present invention is a carbide catalyst that contains at least elements (a transition metal element, In, C) or (a transition metal element, Sn, C), and in particular, it is preferable for the transition metal element to be Fe, Co or Ni. In addition to this carbide catalyst, a metal catalyst of (Fe, Al, Sn) and (Fe, Cr, Sn) are effective. From among these, catalysts such as Fe3InC0.5, Fe3InC0.5Snw and Fe3SnC are particularly preferable. The wire diameter and the coil diameter can be controlled by using a catalyst where any of these catalysts is carried by a porous carrier.

摘要： A material gas and a catalyst are introduced through a material supplying tube path and a catalyst supplying tube path together with a carrier gas into a reactor equipped on its outer periphery with a heat applicator for thermally decomposing the material gas. The reactor has a convention regulator fitted to the discharge end of the catalyst supplying tube path. The convection regulator covers an edge side of the reactor to regulate gas flow in the reactor so that the flow does not reach the edge side. Due to this, a convection state can be efficiently produced in a reaction region. Consequently, it becomes possible to prevent contamination defect caused by accumulation/adherence of concretion of catalyst, which was generated by aggregation of cooled catalyst in the low-temperature region of the reactor and a decomposition product of the material gas. Thus the efficiency of carbon nanostructure production can be improved.
