Embodiment Construction

[0043] Using the method described in the present invention, 9 batches of mesophase carbon microspheres were prepared. According to the above process steps, raw material preparation, polymerization reaction, separation of polymerization reaction products, and drying are carried out successively, and the mesophase carbon microspheres of the present invention are obtained after drying. The raw material composition and its proportioning ratio are shown in Table 1, the polymerization reaction, separation and drying parameters are shown in Table 2, and the particle size and yield of the obtained mesophase carbon microspheres are shown in Table 3.

[0044] For comparison, three batches of mesophase carbon microspheres were prepared by using other production methods in the prior art at the same time, and their relevant parameters are also listed in Table 1, Table 2 and Table 3 respectively. Table 1 Embodiment and comparative example raw material composition and its proportioning (wt %...

Abstract

An intermediate-phase carbon microspheres (0.1-100 microns) is prepared through preparing raw material composed of basic material material and catalyst, polymerizing reaction, separating the resultant and drying. The said basic raw material is aromatic heavy oil and/or asphalt. The said catalyst is chosen from the oxides of Fe, Ni and Co. Its advantages are high output rate (20-70% and controllable granularity.

Description

technical field [0001] The invention belongs to the field of carbon materials, and mainly relates to the preparation of mesophase carbon microspheres. Background technique [0002] Mesophase carbon microspheres are one of the key new carbon materials developed in the field of carbon materials. It is a key material for the breakthrough and development of related cutting-edge technologies. Mesophase carbon microspheres can be used in various functional materials, and its graphitized products are excellent negative electrode materials for lithium-ion batteries. Special carbon products made from mesophase carbon microspheres have ultra-fine structure and excellent isotropy, oxidation resistance and ablation resistance, and can be used as various structural components. [0003] The production of earlier mesophase carbon microspheres was mostly carried out without using a catalyst, so the polymerization reaction time was long, the temperature was high, and the product yield was l...
