Abstract
The invention provides a process for producing carbon nanotubes which includes supplying a continuous fluidized feed of a catalyst and at least one hydrocarbon to a reactor operating under conditions suitable to produce carbon nanotubes. The fluid is made to flow though the reactor with a swirling motion which ensures that the internal surfaces of the reactor are cleaned of deposits.
