Activated carbon according to appearance shape: powdered activated carbon, granular activated carbon, columnar activated carbon, spherical activated carbon, etc.

Today I will mainly talk about spherical activated carbon:

The body structure of Spherical Active Carbon (SAC) contains at least one layer of spherical shell made of activated carbon material. Inside the spherical shell is a spherical core body. It can be made of inorganic materials different from the spherical shell material. The diameter of the spherical shell can be up to 10mm, the wall thickness of the spherical shell is not less than 0.5mm, preferably 1-1.5mm.

Spherical Activated Carbon

Spherical activated carbon, because the inner core can be made of inorganic materials different from the spherical shell material, the specific surface area of spherical activated carbon

It can be as high as 500-1000m²/g, which is conducive to giving full play to the performance of the spherical activated carbon material. In addition, because the fluid flow channel formed between the spherical activated carbon has good hydrodynamic properties and the pressure drop of the fluid passing through the activated carbon layer is small, it is especially suitable for fixed bed gas treatment devices with a large activated carbon stacking layer in the bed.

In a broad sense, spherical activated carbon refers to activated carbon that forms a "spherical" shape; in a narrow sense, if it is distinguished by raw materials, it is mainly "natural spherical activated carbon" processed from asphalt-based and resin-based raw materials.

Wood base, coal base:

This kind of spherical activated carbon is made of coal or wood activated carbon powder added with a binder and then pressed into shape. Most of them are in the shape of irregular ellipses. Because coal-based and wood-based activated carbon has a lot of ash and low hardness, its general application scenarios are relatively common: it is mainly used for water purification and gas treatment; some high-end products are used to purify blood;

Asphalt base, resin base:

This kind of spherical activated carbon has high hardness, low ash content, smooth and shiny surface, very high degree of sphericity, and particle sizes ranging from 0.1mm to 1mm. The world's pitch-based spherical activated carbon is mainly produced in Japan, and the resin-based ones are mainly produced in China and Europe. The activated carbon produced by these two materials has a history of many years and is mostly used in high-end and fine fields.

1.a) Use petroleum asphalt as raw material and use independent technology to create activated carbon BAC with excellent sphericity:

Due to its high strength and high fluidity, it is widely used in various fields as a material for air deodorization, exhaust gas adsorption, water purification, etc.

1) High-density filling possible: The volume density is large and high-density filling is possible. It has stronger adsorption capacity than coal-based activated carbon or coconut shell activated carbon of the same volume.

2) High fluidity: high fluidity, so it can be spread throughout complex-shaped containers

3) Low dust: no adhesive is used, thus achieving high strength and high wear resistance, thereby suppressing the generation of dust

4) Good particle size uniformity: Since the particle size of each grade is uniform, it can exert stable performance



1.b) Acarbon SP series is the latest generation of spherical activated carbon made from special ionic resin and processed using the world's leading spherical activated carbon production technology.

It has high strength (hardness), high purity, low ash content and low impurities; the surface is very smooth and bright, with high sphericity and particle size of 0.1mm~0.9mm.

If spherical activated carbon is made of resin, its characteristics are as follows:

1) 100% does not contain harmful substances: If the raw materials are well controlled, they will not contain heavy metals and other toxic chemical components from the source, so there will be almost no harmful substances to the human body;

2) Low ash content: Using advanced technology, the resin is made into spherical carbon. Since there are few impurities, the ash content of the activated carbon itself will be very low.

3) Strong strength: After carbonization, the strength of the carbon molecules of spherical carbon is enhanced. For example, if the density is the same, the strength will be higher than other similar products.

Application fields of spherical activated carbon made of resin:
1.Solvent recovery
In industry, most organic solvents are used in various forms. While producing the required qualified products, more organic solvents are discharged into the atmosphere, causing pollution, and social conflicts arise. At this time, a Japanese chemical company used spherical activated carbon as a solvent recovery device. By establishing up to 400 sets of devices, it realized solvent recovery for domestic and foreign electrical appliances, chemicals, pharmaceuticals and other industries, and achieved energy saving.dorization, etc.

2.Adsorption treatment of filters, etc.
Due to its characteristics of high purity, low dust, spherical shape, low pressure loss and super purification ability, spherical activated carbon has been used in the fields of adsorption materials for clean room filters in the semiconductor industry, gas treatment of electronic devices, etc.

3.Water treatment
Activated carbon adsorption treatment is a branch of water treatment. With the strengthening of water pollution and related management measures, the demand for activated carbon is also increasing. In activated carbon adsorption treatment, the fluidized bed method shows excellent decontamination efficiency. Water purification plants using spherical activated carbon as the adsorbent in the fluidized bed method have been effective for more than 10 years. In addition, spherical activated carbon is also used in pure water production equipment and drainage treatment equipment due to its high purity, low dust, and wear resistance.

4.Catalyst carrier:
Spherical activated carbon has developed pores, large specific surface area and thermal stability, and is an excellent catalyst carrier. Catalysts can be supported by immersing activated carbon in an aqueous solution of metal salts. In order to uniformly disperse the surface-oxidized activated carbon, the performance as a carrier is determined by the pore structure and surface chemical structure.

Activated carbon as a catalyst support offers the potential to improve industrial process efficiency and product quality, underscoring the importance of activated carbon in this field

5.Medical purposes:
In the medical field, because spherical activated carbon is at the micron level, it has no color and no toxic effects, so it can be taken by the human body for a long time. It can follow food into the human intestine without harming human organs, and is finally eliminated from the human body. It can accurately absorb urinary toxins in the intestines.

Through the human body and blood, spherical activated carbon takes urinary toxins out of the body, effectively preventing the accumulation of toxins in the body. This is the working principle of the Japanese product KREMEZIN; clinical studies have shown that KREMEZIN prolongs the dialysis introduction cycle, reduces the pain and harm caused to patients by reducing the number of dialysis sessions, and at the same time greatly saves medical expenses.

6.Personal protective clothing, gas masks, gas cans
Chemical protective clothing made of spherical carbon is light in weight, has good breathability, low water vapor resistance and good dynamic protection against chemical warfare agents. It can also provide good comfort. Protective clothing based on spherical carbon can be used after multiple washings. The use of spherical carbon protective clothing can overcome the shortcomings of brittle and fragile carbon fiber fabrics and limited filling capacity.

7.Polysilicon Production

In the production of solar polysilicon, spherical activated carbon, especially the spherical activated carbon made of resin, is indispensable for the production of high-quality products because of its strong strength, pure purity, high wear resistance, less dust, and very low impurities. One of the highest quality polysilicon materials.



Now let's summarize the wide range of uses of spherical activated carbon.

In terms of environmental protection, spherical activated carbon is used to purify air and treat water. There are many harmful substances in the air and water, and spherical activated carbon can effectively adsorb and remove them. For example, harmful substances such as formaldehyde, benzene and ammonia contained in the air. In the chemical industry, another good application of spherical carbon is as a catalyst carrier to improve the selectivity and activity of the catalyst. In the field of energy storage in supercapacitors and batteries, spherical activated carbon performs equally well.



Spherical activated carbon is mostly used in industrial applications, but the use of spherical activated carbon in our daily lives cannot be ignored. Electrical appliances such as air purifiers and water purifiers that are often used in our homes are very effective in ensuring our daily life and health; they also perform well in terms of food preservation and medicine.



All in all, as a new type of activated carbon material, spherical activated carbon has a very wide range of applications through its excellent adsorption capacity; science is changing with each passing day, environmental protection and healthier living have always been people's unremitting pursuit, so the application of spherical activated carbon is still With continuous development, I believe that in the near future, there will be deeper applications for spherical carbon.
