Nut Shell Granular Activated Carbon
Fruit shell activated carbon is manufactured via steam activation of carbon-rich fruit shells, commonly apricot shell, peach pit and walnut shell. It has a high affinity for small-molecule contaminants including VOCs, residual chlorine, odors and trace organic compounds in both gas and liquid applications.
What is Nut Shell Granular Carbon
Nut shell activated carbon is a type of activated carbon. It is made from raw materials such as coconut shells, walnut shells, apricot shells, and peach shells through a series of processes including high-temperature carbonization and activation. It is a porous adsorption material. The most common and highly effective type on the market is coconut shell activated carbon, which also belongs to shell activated carbon. It is mainly applied in fields such as drinking water treatment, industrial wastewater purification, gas separation and purification, organic solvent recovery, and de-colorization and deodorization in the food and pharmaceutical industries.
It outperforms coal-based and wood-based activated carbon and is widely adopted for rigorous purification applications.
- Micropore-dominated, good small-molecule adsorption
- High hardness, low abrasion loss
- Low ash, stable performance
- Natural shell feedstock, eco-friendly
