Abstract

The present invention relates to a continuous manufacturing apparatus for a carbon nanotube having gas separation units and a continuous manufacturing method for a carbon nanotube using the same. According to the present invention, the present invention has an effect to provide the continuous manufacturing apparatus of the carbon nanotube and continuous manufacturing method using the same, in which it makes possible to perform a rapid processing; has excellent productivity and excellent conversion rate of carbon source; can significantly reduce the cost of production; can reduce energy consumption because a reactor size can be decreased as compared with capacity; and a gas separation unit that not generate a waste gas.

First claim

The invention claimed is:

1. A continuous manufacturing method of a carbon nanotube, comprising:
i) producing the carbon nanotube by providing and reacting a reaction gas including a carbon source, a reducing gas, and an inert gas with a catalyst, and cooling the produced carbon nanotube to a range of 40 to 50° C. in a heat exchanger, wherein the reaction gas, the reducing gas, and the inert gas comprise a mixed gas;
ii) separating the mixed gas from the carbon nanotube, thereby…
