Abstract
The present invention relates to a carbon nanotube preparation method and system, which may improve the overall efficiency and economic feasibility of a reaction by collecting fine particles including carbon nanotube particles that have not grown enough and an unreacted catalyst produced during and after the reaction by using a separator at the exterior of a fluidized bed reactor, and then, injecting the fine particles as a bed prior to a subsequent cycle.
