The difference between non activated carbon and activated carbon

The difference between general charcoal and activated carbon:

1. With different processing technology, bamboo charcoal only goes through the carbonization stage, and activated carbon needs to go through activation, pickling and drying stages in addition to the carbonization process.

2. The microstructure is very different: the pore diameter of bamboo charcoal is larger than that of activated carbon.

3. The specific surface area is different. The specific surface area refers to the size of the surface area occupied by the unit mass.

4. There is a big difference in hardness. Bamboo charcoal has high density, high hardness, and is not easy to break. It is suitable for wear-resistant home textile products; the hardness of activated carbon of different materials is very different, the hardness of coconut shell activated carbon is high, and the activated carbon produced from bamboo has light specific gravity and softness. , It is fragile, so it is not suitable for products with high abrasion resistance requirements.

5. The production cost varies greatly. Bamboo charcoal requires only one carbonization process, while activated carbon also requires an activation process. The cost is much higher than bamboo charcoal, about 35 times that of bamboo charcoal. Therefore, the product price is 3-5 times that of bamboo charcoal.

6. The raw material and its consumption are different. The raw material consumption of activated carbon is generally 3-5 times higher than that of bamboo charcoal. For example, 6t (ton) of bamboo can make 1t of bamboo charcoal, but 3-5t of bamboo charcoal can process 1t of bamboo activated carbon. Of course, the raw material cost of coconut shell activated carbon will be higher, but the better the effect.

7. Different shapes of bamboo charcoal in different shapes, including tube charcoal, flake charcoal, crushed charcoal, granular charcoal, charcoal powder, etc., with a wide range of applications. and many more

8. The pores of bamboo charcoal with different adsorption objects are mainly macropores, while activated carbon is very different. Physically activated activated carbon is dominated by micropores, and chemically activated activated carbon is dominated by macropores. Different activation processes The activated carbon produced is quite different.

Bamboo charcoal mainly adsorbs some macromolecular substances, including many microorganisms. Activated carbon has different pore structures and is used in different fields according to different adsorbed species. But for substances with small molecular diameters (such as formaldehyde, benzene, ammonia and other harmful gases), the adsorption of activated carbon is several times stronger than that of bamboo charcoal. Moreover, the adsorption of activated carbon is very specific, and different pore sizes are used to adsorb different substances.
