Why carbon black and coke are not adsorptive
Carbon black and coke are carbon materials, but their adsorption properties are very different. Carbon black has strong adsorption and can be used to prepare various adsorbents, while coke has almost no adsorption. Why is this?
Carbon black and coke are carbon materials, but their adsorption properties are very different. Carbon black has strong adsorption and can be used to prepare various adsorbents, while coke has almost no adsorption. Why is this?
We need to understand the basic principles of adsorption. Adsorption refers to the phenomenon that when a substance is in contact with a solid surface, the substance is attached to the solid surface due to the interaction between the chemical or physical properties of the surface and the substance. Adsorption is divided into two kinds of physical adsorption and chemical adsorption. Physical adsorption refers to the physical forces such as van der Waals force and electrostatic force between the substance and the solid surface, while chemical adsorption refers to the chemical bond between the substance and the solid surface.
The adsorption properties of carbon black and coke are different, mainly due to their different surface properties. The surface of carbon black is rich in active functional groups, such as hydroxyl, carboxyl, phenol, etc. These functional groups can react with various substances or physically adsorb, thus showing strong adsorption. The surface of coke is relatively simple, mainly composed of carbon atoms, there is no rich functional groups, so there is almost no adsorption.
In addition, the preparation method of carbon black and coke will also affect their surface properties and adsorption properties. Carbon black is usually prepared by pyrolysis of organic matter. A large amount of gas and liquid by-products will be produced during the pyrolysis process. These by-products will form holes and functional groups on the surface of carbon black, thereby increasing the surface area and activity of carbon black. Coke, on the other hand, is prepared by high-temperature calcination of coal or coke, and the impurities and functional groups in the coal or coke are burned out during the calcination process, so that the surface of the coke becomes relatively simple and has almost no adsorption.
The difference in adsorption properties of carbon black and coke is mainly due to their different surface properties. Carbon black has rich functional groups and pore structure, large surface area, so it has strong adsorption, while coke surface is relatively simple, almost no adsorption. This difference is not only related to the nature of the material itself, but also to the preparation method.

The "ground refinery" has faded from the spotlight, and how to recycle waste tires with low consumption and harmlessness has attracted much attention. On the other hand, the state recently added waste tires, waste rubber products production of recycled oil, cracking carbon black tax rebate, but also further stimulate the enthusiasm of industrial capital entry.

Introduction of special rubber materials-chlorosulfonated polyethylene rubber (CSM)
Chlorosulfonated polyethylene (alias: Haibolong Haibolong hypalon) is a kind of special rubber made by chlorination and chlorosulfonation of polyethylene. After chlorination and sulfonation of polyethylene, the regularity of its structure is destroyed, and it becomes soft and elastic chlorosulfonated polyethylene rubber at room temperature.
