Abstract

The invention aims to provide complete equipment for preparing an intermediate phase carbon microball. The complete equipment is characterized by comprising a catalyst pretreatment device, wherein the catalyst pretreatment device comprises a cylinder body 1 and a jacket 2; a feeding bin 3 and a circulating smoke-abating pipe are arranged on the upper end of the cylinder body 1, a material discharge port 9 is arranged on the lower end of the cylinder body; a preferably selected jacket is provided with a water inlet 14 and a water outlet 15. The complete equipment provided by the invention heats, melts and pretreats the catalyst through the catalyst pretreatment device, and is beneficial to the uniform mixing with reaction raw materials (such as asphalt), thus the enclosed feeding and efficient catalysis are realized, the defect of ignition of a mixed liquid spraying tank caused by nonuniform mixing of the catalyst and raw materials, partial overheating, over severe catalyst reaction is overcome, and the complete equipment for preparing the intermediate phase carbon microball has the advantages of simplicity in operation, no dust, low preparation cost, environment pollution prevention and the like.

Description

technical field [0001] The invention relates to a complete device for preparing mesophase carbon microspheres, a catalyst pretreatment device and a preparation method. Background technique [0002] Mesophase carbon microspheres have outstanding advantages such as high-rate discharge performance and high safety, and have become the most important anode materials for lithium-ion power batteries at present. [0003] The existing preparation methods of mesophase carbon microspheres include thermal condensation polymerization method, emulsion method, suspension method and so on. Wherein, the emulsion method is developed by Japan's Kodama et al. (Kodama M, Fujirua T, Esumi K et al.Carbon, 1988, 26 (4): 595), this method dissolves the polycyclic aromatic compound in a certain amount of heat-stable In the medium (such as silicone oil), after heat treatment, the emulsified mesophase spheres are then carbonized and graphitized to obtain mesophase carbon microsphere material products....
