Abstract
Provided is a method of producing carbon nanotubes by supplying a catalyst and a carbon source to a fluidized bed reactor. The fluidized bed reactor has an expanded zone. A flow velocity (linear velocity) of a raw material supplied to the fluidized bed reactor is equal to or higher than a terminal velocity of an internal material in the fluidized bed reactor.
