On spherical activated carbon

Spherical active carbon (SAC) has at least one layer of spherical shell made of activated carbon material. The spherical inner core is inside the spherical shell, which can be made of inorganic materials different from the spherical shell material. The diameter of the spherical shell can reach 10mm, and the wall thickness of the spherical shell is not less than 0.5mm, preferably 1-1.5mm. As the inner core of the spherical activated carbon disclosed by the utility model can be made of inorganic materials different from the spherical shell materials, the specific surface area of the spherical activated carbon can be as high as 500-1000m2/g, which is conducive to giving full play to the performance of the spherical activated carbon composition materials.

In addition, because the fluid channel formed between the spherical activated carbon has good hydrodynamic performance, and the pressure drop of the fluid through the activated carbon layer is small, it is especially suitable for the fixed bed gas treatment device with high stacking height of activated carbon in the bed. Spherical activated carbon is a kind of activated carbon with high sphericity prepared from petroleum asphalt. In addition to the adsorption properties of activated carbon, it also has many other characteristics. 1. Small particle, high filling property, 2. High fluidity, 3. High purity, low ash powder, 4. High strength, high wear resistance, 5. Spherical activated carbon with narrow particle size distribution adopts the production method using asphalt as raw material, and the product performance is stable. In addition, sac is characterized by the use of high-quality asphalt, its spheroidization process does not use binder, and it is made by maintaining uniform non melting and activation in the flowing state. According to the average particle size classification, BAC is divided into 4 categories. 1. 0.2-0.4mm 2 0.4-0.6mm 3 0.6-0.9mm 4 0.9mm and above
