Fruit shell activated carbon is an adsorbent material made from various fruit shells (such as coconut shells, walnut shells, apricot shells, etc.) through a series of fine processing. It appears as black granules or powder, with a highly developed internal pore structure. These pores are interconnected, forming a huge specific surface area, which endows fruit shell activated carbon with strong adsorption performance. It is an efficient and environmentally friendly adsorbent, playing a key role in many fields.
Particle size: If it is granular, the particle size is generally about 0.5 - 2.0mm, and the particles are uniform, which is convenient for filling and use in adsorption equipment; if it is powdery, most of it can pass through 80 - 200 mesh sieve (particle size less than 0.18 - 0.075mm). Fine particle size helps better dispersion in liquids or gases, increases the contact area, and improves adsorption efficiency.
Specific surface area: The specific surface area is relatively large, usually between 900 - 1500m²/g. The vast specific surface area provides abundant sites for adsorption, enabling it to adsorb a large amount of impurities, pigments, odorous substances and harmful gases, etc.
pH value: The pH value range is roughly between 4 - 10. Within this range, it can adapt to many different adsorption environments and will not cause significant interference to the acidity and alkalinity of the adsorption system.
Strength (applicable to granular form): For granular fruit shell activated carbon, strength is an important indicator. It has good mechanical strength, and the compressive strength can generally reach more than 80% - 95%. During use, such as being impacted by air flow or liquid flow in the adsorption tower, it is not easy to break, can maintain a good particle shape, and ensure the stability of the adsorption process.
