Activated carbon expands the internal space through the carbonization activation process, and the adsorption performance is greatly improved. As a common adsorbent in the industry, it has the following advantages:
Relatively developed pore structure and large specific surface area
Activated carbon has a well-developed pore structure. In addition to active molecular sieves, there are also pores with a wider range of pores, with pores with different pore sizes, which can adsorb substances with different molecular sizes. At the same time has a large number of micropores, so the specific surface is proportional to the adsorption capacity
Surface characteristics of activated carbon
The surface properties of ningxia yongruida carbon will change with the different activation conditions. Activated carbon activated by high temperature water vapor has alkaline oxides attached to the surface, while activated carbon activated by zinc chloride contains acidic oxides on the surface, which is activated by zinc chloride. Activated carbon has strong adsorption capacity for alkaline compounds. Activated carbon has different surface chemistry, pore size distribution and pore shape, which is one of the reasons why activated carbon has selective adsorption.
Catalytic properties
Activated carbon is used as a contact catalyst in various isomerization, polymerization, oxidation and halogenation reactions. Its catalytic activity is due to some physical and chemical properties of carbon. In the chemical industry, activated carbon often uses a catalyst as a carrier, that is, a substance with catalytic activity is deposited on it and used as a catalyst together. At this time, the role of activated carbon is not limited to supporting the activator, it has a significant impact on the activity, service life and selectivity of the catalyst, and it has a catalytic effect.
Chemically stable and easy to regenerate
Activated carbon is chemically stable, resistant to acids and alkalis, so it can be used in a large pH range; 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 Its catalytic activity is often used as a catalyst or carrier in organic synthesis. When activated carbon fails, it can be repeatedly regenerated by various methods to restore its adsorption capacity and reuse it in production. If the regeneration is successful, the original adsorption level can be reached.www.wyactivatedcarbon.com
