Abstract
A synthesis reactor for producing carbon nanotubes. The reactor includes a main reactor, a feeder, a settler, an air inlet device, and a product outlet. The main reactor communicates with the settler in the form of a communicating vessel. The feeder communicates with the settler via a catalyst inlet. The air inlet device is disposed under the settler. The wall of the main reactor is provided with a heat exchanger. The product outlet is disposed at the lower part of the main reactor. A method for producing a carbon nanotube, includes: 1) drying red mud for 1 to 4 hour(s) at the temperature of between 101° C. and 109° C.; 2) smashing and sieving the red mud through a 200-mesh sieve to yield a catalyst; and 3) adding the catalyst to a synthesis reactor.
