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.Advantageously, the apparatus and method for continuously producing carbon nanotubes enable rapid processing, exhibit superior productivity and excellent conversion rate of a carbon source, significantly reduce production costs, reduce energy consumption due to decrease in reactor size relative to capacity, and generate little or no waste gas and are thus environmentally friendly.
