    • PURPOSE: A continuous manufacturing apparatus of carbon nano-tubes with a gas separating unit and a continuous manufacturing method of the carbon nano-tubes using the same are provided to hardly generate waste gas and to reduce the size of a reactor in comparison with the capacity of the reactor. CONSTITUTION: A continuous manufacturing method of carbon nano-tubes includes the following: the carbon nano-tubes are generated by reacting a catalyst and reaction gas containing carbon sources, reduction gas, and inert gas; the generated carbon nano-tubes are separated from mixed gas; the separated mixed gas is filtered to remove a part or whole of the reduction gas; and the filtered mixed gas is re-circulated to the carbon nano-tube generating process. A cooling process is further implemented before the generated carbon nano-tubes and the mixed gas are separated.
