Abstract
A method of producing fibrous carbon nanostructures uses a fluidized bed process, and comprises supplying a source gas to a reaction site in which a supported catalyst having a particulate carrier and a catalyst supported on a surface of the carrier is fluidizing, to form fibrous carbon nanostructures on the catalyst of the supported catalyst, wherein the source gas contains a double bond-containing hydrocarbon and carbon dioxide, and a content of the carbon dioxide is 0.3 vol % or more with respect to a total volume of the source gas.
