Abstract

The invention belongs to the technical field of materials and particularly relates to a synthetic method for a carbon nano tube. The synthetic method includes the steps that 1, pulverized coal and water are mixed into slurry in slurry synthesizing equipment, the slurry generates water gas in a water gas generating device, and the water gas is stored in a water gas storage tank for use; 2, a catalyst is dissolved in a solvent and stored in a catalyst storage tank for use; 3, the water gas and the catalyst are controlled to be fed into a synthetic furnace in a pumping mode, the carbon nano tube is obtained, and the proportion of carbon nano tube bodies of different shapes in the carbon nano tube is controlled by controlling the flow of the water gas and the catalyst. The preparation method is simple and environmentally friendly, by the adoption of a slurry carbon source and the liquid dissolved catalyst, continuous production can be achieved through pumping, and reaction products are accurately controlled.

Description

technical field [0001] The invention relates to the field of carbon nanotube synthesis and carbon nanotube synthesis equipment, in particular to a single-wall carbon nanotube, a preparation method of a single-wall carbon nanotube / whisker carbon nanotube blend material and corresponding synthesis equipment. Background technique [0002] Carbon nanotubes are a new type of carbon material discovered in 1991. According to the number of layers of graphite sheets, it can be divided into: single-walled carbon nanotubes and multi-walled carbon nanotubes. Single-walled carbon nanotubes have a small diameter distribution range, few defects, high uniformity, and excellent thermal and electrical conductivity. However, it is difficult to achieve continuous production at present, and it is easy to entangle and disperse. The requirements are strict and it is difficult to be widely used. [0003] The typical diameter of multi-walled carbon nanotubes is 2-100nm, the length is generally on ...
