At present, the biomass that can be used to make activated carbon after carbonization includes: wood, fruit shells, and crop straw.

First of all, wood: rich in wood fiber and high in carbon content. The structure is relatively uniform, and the pores of the activated carbon produced are relatively regular.

For example, pine and birch, pine wood has a moderate lignin content. After carbonization and activation treatment, activated carbon with good adsorption performance can be obtained. For birch, the texture is fine and the wood is relatively hard. The activated carbon formed after carbonization has developed pores and a large specific surface area, and has a strong adsorption effect on impurities in gas and liquid.

Secondly, fruit shells: Fruit shells are widely available, low in cost, usually have high hardness and strength, and are not easy to break during the production process.

For example, coconut shells and walnut shells, coconut shells are a high-quality activated carbon principle with high carbon content, rich microporous structure, and excellent adsorption performance. Coconut shell activated carbon is widely used in water treatment, air purification, food processing and other fields; Walnut shells are hard in texture and contain a large amount of lignin and cellulose. After treatment, they can be made into activated carbon with high adsorption capacity for removing heavy metal ions and organic pollutants in water.

Finally, there are crop straws. Crop resources are rich, highly renewable, and contain a certain amount of cellulose, hemicellulose, and lignin.

For example, wheat straw and corn straw. Wheat straw is the residue after wheat harvest. It is large in quantity and easy to obtain. Wheat straw can be converted into activated carbon through appropriate processing technology. Wheat straw activated carbon has a certain adsorption effect on pesticide residues, heavy metal ions, etc. Corn straw is rich in cellulose and hemicellulose. After carbonization and activation, it can be made into activated carbon with certain adsorption properties. It has potential application value in agricultural waste treatment and environmental governance.
