Spherical Active Carbon (SAC) is a spherical shell made of at least one layer of activated carbon material, which is a spherical inner core body which can be made of an inorganic material different from the spherical shell material, the diameter of the spherical shell Up to 10mm, spherical shell wall thickness of not less than 0.5mm, preferably 1-1.5mm.

The spherical activated carbon disclosed in the utility model can be prepared by the inorganic material different from the spherical shell material, and the specific surface area of ​​the spherical activated carbon can be as high as 500-1000m² / g, which is beneficial to the performance of the spherical activated carbon constituent material. In addition, due to the hydrodynamic performance of the fluid channel formed between the spherical activated carbon and the pressure of the fluid through the activated carbon layer is reduced, it is particularly suitable for a fixed bed gas treatment apparatus having a large height of the activated carbon stack in the bed.

Spherical activated carbon is made of petroleum asphalt as raw material to produce high spherical activated carbon. In addition to the activated carbon has the adsorption properties, but also has a variety of other features.

1 small particles, high filling

2 high mobility

3 high purity, low ash powder

4 high strength, high wear resistance

5 Narrow particle size distribution

Spherical activated carbon using asphalt as raw material production methods, product performance and stability. In addition, SAC is characterized by the use of high-quality asphalt, the ballification process without the use of adhesives, and in the flow state to maintain a uniform non-melting and activation of the system.

According to the average particle size classification, BAC is divided into four categories.

1. 0.2-0.4mm

2. 0.4-0.6mm

3. 0.6-0.9mm

4. 0.9mm and above
