Abstract
Disclosed are an apparatus and method for continuously producing carbon nanotubes. More specifically, disclosed are an apparatus for continuously producing carbon nanotubes including i) a reactor to synthesize carbon nanotubes, ii) a separator to separate a mixed gas from the carbon nanotubes transferred from the reactor, iii) a filter to remove all or part of one or more component gases from the separated mixed gas, and iv) a recirculation pipe to recirculate the filtered mixed gas to the reactor for carbon nanotubes.
