|Title:||METHOD FOR MANUFACTURING MULTI-WALL CARBON NANOTUBES USING CONTINUOUS TYPE PROCESS|
An embodiment of the present invention provides a method for manufacturing multi-wall carbon nanotubes, the method comprising the steps of: (a) dissolving a metal precursor in a solvent to prepare a precursor solution; (b) perform thermal decomposition while spraying the precursor solution into a reactor, thereby forming a catalyst powder; and (c) introducing the catalyst powder into a fluidized-bed reactor heated to 600-900°C and spraying a carbon-based gas and a carrier gas to synthesize multi-wall carbon nanotubes from the catalyst powder, wherein steps (a) to (c) are performed in a continuous type and wherein the catalyst powder contains metal components according to equation 1 below.
