Problems solved by technology

Because the horizontal reactor is placed horizontally, the product that enters and reacts horizontally cannot reach the other end of the same height in time and is blocked, resulting in interruption of the reaction, high reaction temperature, and the reaction system is limited by the pressure. The diameter of the reaction tube, The rate of product generation is slow; while the vertically placed vertical reactor generates upward pressure due to the vaporization of the large liquid in the reaction furnace, which causes the light-weight carbon nanotube macroscopic tube continuum to easily accumulate at the lower end of the reaction tube The exit of

Abstract

The invention discloses a method for tilting preparation of a carbon-nanotube macrotube continuous body, and relates to the technical field of nanomaterials. A horizontal high-temperature tubular reaction furnace is separated from a horizontal base, and a horizontal reactor is tilted with a certain angle, so that not only can the continuous degree and the preparation speed be achieved during preparation of the carbon-nanotube macrotube continuous body, but also the temperature range during the preparation of the continuous body can be further extended through the method, the diameter of a reaction tube of the reaction system is further increased, and the preparation efficiency is greatly improved. The method has the advantages of simple device, easily available raw materials, low cost, and no pollution to the environment; by adopting inert gas protection, no obvious flammable and hazardous raw material exists; and the product is easy to treat, high in yield, and simple in equipment, can be continuously operated, and is suitable for mass production.
