What are the product performance advantages of activated carbon?

1. It has a relatively developed pore structure and a large specific surface area.

    Activated carbon has a well-developed pore structure. In addition to activated molecular sieves, it has a wide pore size distribution range, has pores with different pore sizes, and can adsorb various substances with different molecular sizes. At the same time, it has a large number of micropores, so the specific surface area is large and the adsorption force is also large.

2. Surface characteristics of activated carbon

    The surface properties of activated carbon vary depending on the activation conditions. The surface of activated carbon activated by high-temperature water vapor mostly contains alkaline oxides, while the surface of activated carbon activated by zinc chloride mostly contains acidic oxides. The latter has special adsorption capacity for alkaline compounds. big. Activated carbon has different surface chemical properties, pore size distribution and pore shape, which are the main reasons for the selective adsorption of activated carbon.

3. Catalytic properties

    Activated carbon is used as a contact catalyst in various isomerization, polymerization, oxidation and halogenation reactions. Its catalytic activity is due to the surface and surface compounds of the carbon, as well as the ash content, etc. Activated carbon is often used as a catalyst carrier in the chemical industry, that is, catalytically active substances are deposited on activated carbon and used together as a catalyst. At this time, the role of activated carbon is not limited to loading activator. It has a significant impact on the activity, selectivity and service life of the catalyst. It also has the role of promoting catalysis.

4. Chemically stable and easy to regenerate

    Activated carbon has stable chemical properties and is resistant to acid and alkali, so it can be used in a wide range of pH; activated carbon is insoluble in water and other solvents and can be used in aqueous solutions and many solvents; activated carbon can withstand high temperature and high pressure because of its It has great catalytic activity and is often used as a catalyst or carrier in organic synthesis. When activated carbon expires, it can be regenerated multiple times through various methods to restore its adsorption capacity and then be used for production. If regeneration is successful, the original adsorption level can be achieved.
