Abstract: The present disclosure provides an apparatus capable of continuously producing carbon nanotubes having high crystallinity, a low residual catalyst content and a high aspect ratio. The apparatus for producing carbon nanotubes includes: a reaction unit configured to synthesize carbon nanotubes (CNTs), a supply unit configured to supply a carbon source to the reaction unit through a supply pipe; and a collection unit configured to collect carbon nanotubes discharged from the reaction unit, wherein the reaction unit may include a chemical vapor deposition reactor.
