A process and equipment for preparing fullerenes by combustion method

Abstract

The invention discloses a novel technology for preparing fullerene through a combustion method, and novel equipment for preparing the fullerene through the combustion method. The novel technology and novel equipment are characterized in that combustion reaction and cracking synthetic reaction are independently carried out, and fuel and carbon-contained raw material are separated in the technical process of preparing the fullerene through the combustion method; the fuel and the carbon-contained material are transferred into different reaction chambers, respectively; and the combustion reaction and the cracking synthetic reaction are carried out in different reaction chambers. The reaction chambers of the novel equipment have horizontal structures comprising three reaction chambers which are sequentially communicated. According to the novel technology and the novel equipment, high-quality fuel and carbon-contained raw material can be rationally selected, therefore, the fuel consumption and the cost of the product are reduced; the yield of the fullerene is improved; the combustion reaction and the cracking synthetic reaction are independently carried out, thus the quantity of input fuel, oxygen-contained gas and carbon-contained raw material can be conveniently changed, and the technical parameters of each reaction chamber can be adjusted according to the requirements of the preparation technology, as a result, the purpose of optimizing the technology for preparing the fullerene can be achieved. With the adoption of the technology and equipment for preparing the fullerene, the fullerene can be continuously and industrially produced in batches with low cost.

Description

technical field [0001] The invention belongs to the technical field of inorganic chemistry, and relates to a new process and new equipment for preparing fullerenes by using a combustion method, in particular to a new process preparation method and device for preparing fullerenes in a three-chamber reaction chamber. Background technique [0002] The unique molecular structure and exotic physical and chemical properties of fullerene make it have very important application value and market prospect in many disciplines and fields such as energy, superconductivity, electronics, magnetism, optics, materials and medicine. Now with the continuous deepening of application research, the application field of fullerene is also expanding, and some fullerene products have entered the market. [0003] Although fullerene has high application value and great market potential, it is difficult to prepare in large quantities. At present, most of the preparation methods are small-batch and high...
