Types And Uses Of Activated Carbon

Activated carbon is a kind of black porous solid carbon, which is produced from coal by crushing, molding or carbonization and activation with uniform coal particles. The main component is carbon, which has strong adsorption properties and is an industrial adsorbent with a wide range of uses. There are many types of Activated Carbon, which are suitable for various fields such as factories, households, and automobiles. Below, Zhelang will introduce to you: the types and uses of activated carbon
Activated carbon is divided into five categories according to the material
1. Coconut shell charcoal
Coconut Shell Activated Carbon is made of high-quality coconut shells from Hainan, Southeast Asia and other places. The raw materials are screened, steam carbonized, refined, and then processed by a series of processes such as impurity removal and activation screening. Coconut shell activated carbon is black granular, with developed pore structure, high adsorption capacity, high strength, stable chemical performance and durability. Widely used in metallurgy and Chemical Industry, petroleum and electric power, food and beverage, drinking water, purified water, deep purification of industrial water and refining of precious metals. It has the effects of decolorization, deodorization, adsorption and turbidity, and has a better effect when combined with zeolite and molecular sieve. Very popular among users.
2. Shell charcoal
Shell activated carbon is mainly made of fruit shells and wood chips, which are processed by carbonization, activation and refining. It has the characteristics of large specific surface area, high strength, uniform particle size, well-developed pore structure, and strong adsorption performance. And it can effectively absorb free chlorine, phenol, sulfur, oil, colloid, pesticide residues and other organic pollution in water, as well as recover organic solvents. It is suitable for decolorization, refinement, purification and sewage treatment of organic solvents in pharmaceutical, petrochemical, sugar, beverage and wine purification industries. Fruit shell activated carbon is widely used in the deep purification of drinking water, industrial water and wastewater, and in the purification of industrial water quality.
3. Wood charcoal
Wood charcoal is made of high-quality wood, which is powdery in shape and refined through high-temperature carbonization, activation and various processes. It has large specific surface area, high activity, developed micropores, strong decolorization power, and large pore structure. Features, large pore structure, can effectively absorb various substances and impurities such as colors in the liquid.
4. Columnar carbon
Using high-quality sawdust and charcoal as raw materials, it is made through crushing, mixing, extrusion, molding, drying, carbonization and activation. Compared with the traditional coal-based columnar carbon, the columnar activated carbon has lower ash content, less impurities, and reasonable pore size distribution, which can achieve maximum adsorption and desorption, thereby greatly improving the service life of the product (average 2-3 years), which is common 1.4 times that of coal-based carbon.
5. Coal-based carbon

This product is made of high-quality anthracite as raw material. The shapes are columnar, granular, powder, honeycomb, spherical and other shapes. It has high strength, fast adsorption speed, high adsorption capacity, large specific surface area, developed pore structure, and large pore size. Between coconut shell activated charcoal and wood activated charcoal. Mainly used for high-end air purification, exhaust gas purification, high-purity water treatment, wastewater treatment, sewage treatment, etc.

Activated carbon classification by use
1. Coal-based Granular Activated Carbon for solvent recovery
It is made of natural high-quality coal and refined by physical activation method. It is black granular, non-toxic and tasteless, with well-developed pores. The distribution of three types of pores is reasonable, and it has strong adsorption capacity. It has a strong adsorption capacity for most organic solvent vapors in a wide concentration range, and is widely used in the recovery of organic solvents such as benzene, xylene, ether, ethanol, acetone, gasoline, chloroform, and tetrachloromethane.
2. Activated carbon for water purification
It is made of high-quality natural raw materials (coal, wood, fruit shell, etc.) and refined by physical activation method. It is black granular (or powdery), non-toxic and tasteless, has the advantages of strong adsorption capacity, fast filtration speed, etc., and can effectively Adsorbing undesirable substances with small molecular structure and macromolecular structure in the liquid phase, it is widely used in the purification and purification of drinking water and the deodorization and purification of industrial wastewater, sewage, and river sewage water quality, and deep improvement.
3. Activated carbon for air purification
Using high-quality coal as raw material, refined by catalytic activation, black columnar particles, non-toxic and tasteless, with strong adsorption capacity and easy desorption, it is widely used in solvent recovery of gas phase adsorption, indoor gas purification, industrial waste gas treatment, flue gas Purification and gas protection, etc.
4. Coal-based granular activated carbon for desulfurization
Using high-quality natural coal as raw material, it is refined by physical activation method. It is black granular, non-toxic and tasteless, has a large sulfur capacity, high desulfurization efficiency, good mechanical strength, small penetration resistance and easy regeneration. Widely used in thermal power plants, petrochemical, gas, natural gas and other gas desulfurization.
5. Fine desulfurization activated carbon
High-efficiency and high-precision gas-phase normal-temperature fine desulfurizer is made of high-quality columnar activated carbon as a carrier, loaded with special catalysts and catalytic aids, dried, screened and packaged. It is mainly suitable for the production processes of synthetic ammonia, methanol, methane, food carbon dioxide, polypropylene, etc. Refined desulfurization can also be used for refined dechlorination and desulfurization of gas, natural gas, hydrogen, ammonia and other gases. It can remove the sulfur content in the gas to 0.05mg/Nm
6. Granular activated carbon for protection
Select high-quality raw materials (coal, fruit shells), use granular activated carbon refined by physical activation as the carrier, and use advanced process equipment and strictly controlled special process conditions to manufacture catalyst carrier carbon. Reasonable pore size distribution, high wear resistance, widely used in phosgene synthesis, polyvinyl chloride synthesis, vinyl acetate synthesis and other industrial catalyst carrier and effective protection against ammonia, hydrogen sulfide, sulfur dioxide, carbon monoxide, hydrocyanic acid, phosgene, benzene Series of products and other toxic gas protection.
