Abstract
A method of producing carbon nanotubes in a fluidized bed reactor includes preparing a carbon nanotube by supplying a catalyst and a carbon source to an interior of the fluidized bed reactor having an internal pressure of 0.5 barg to 1.2 barg (gauge pressure), thereby improving the yield and purity of carbon nanotubes.
