Device and process method for continuously producing carbon nanotubes

Abstract

The invention discloses a device for continuously producing carbon nanotubes, which consists of a feeder, a reduction reactor, a synthesis reactor and a product collector which are connected in series in turn, wherein the reduction reactor is a fluidized bed reactor; and the synthesis reactor is a spouted bed reactor. The invention also discloses a process method for continuously producing carbonnanotubes based on the device. The catalyst reduction and deposition preparation of the carbon nanotubes are respectively realized by the fluidized bed and the spouted bed, so that the process conditions can be regulated in a wider range, the fluidized state of agglomerated nanoparticles in the beds is ensured, and the high-quality carbon nanotubes are continuously produced.

Description

technical field

[0001] The invention relates to the technical field of nanometer materials, in particular to a production device and a process method of carbon nanotubes. Background technique

[0002] Carbon nanotubes have a typical layered hollow structure, and there is a certain angle between the layers that constitute carbon nanotubes. The tube body of carbon nanotubes is a quasi-circular tube structure, and most of them are composed of pentagonal cross-sections. The tube body of carbon nanotubes is a coaxial circular tube consisting of several to dozens of layers of hexagonal carbon ring microstructure units, with a fixed distance between layers, about 0.34nm, and a diameter of generally 2- 20nm; the end cap part is a polygonal structure composed of pentagonal carbon rings, or a polygonal cone-shaped multi-walled structure, which is a one-dimensional quantum material with a special structure. Due to their unique structure, the study of carbon nanotubes has great theoret...
