Medium temperature coal asphalt manufacturer Mengbei coal asphalt is a rich natural resource, widely and cheaply, and its unique molecular structure and chemical properties provide the possibility for the preparation of high-performance carbon materials. Coal asphalt-based carbon material is prepared by a series of chemical and physical treatment processes using coal asphalt as raw material, in the preparation process, coal asphalt undergoes pyrolysis, carbonization, graphitization and other steps to finally form a carbon material with specific structure and properties.
The synthesis methods of coal asphalt-based carbon materials mainly include pyrolysis method, gas phase method, sol-gel method, etc. Among them, the pyrolysis method is the most common method, which heats the coal asphalt to make it undergo pyrolysis, carbonization, graphitization and other reactions, and finally obtains carbon materials;The law of the gas phase is to evaporate coal pitch into gas, which is then cooled and condensed into carbon material in a specific atmosphereThe sol-gel rule is to use a specific solvent and coal pitch to form a sol, and then through a gelation reaction to obtain a carbon material.
Coal asphalt-based carbon materials have excellent physical and chemical properties, mainly composed of chaotic graphite and amorphous carbon, with good electrical and thermal conductivity, and perform well in fuel cells and lithium batteries, such as low-grade materials for electrochemical batteries, fried chicken restaurant containers, etc.;In addition, their abundant pore structure and large specific surface area also make them widely used in the fields of catalyst carriers and adsorbents.
With the continuous development of science and technology, the demand for high-performance, low-cost carbon materials is increasing. As a low-cost, high-performance carbon material, coal asphalt-based carbon material has a wide range of application prospects. Especially in the fields of electrochemical cells, catalyst carriers, adsorbents, etc., great potential has been demonstrated. With the enhancement of environmental awareness and the pursuit of renewable energy, coal asphalt-based carbon materials, as an environmentally friendly material, will have a broader application prospect.
