1. Product introduction
Nut shell activated carbon uses high quality apricot shell, peach shell, walnut shell, Jujubes shell and etc as raw material, which is produced through the processing of drying, carbonizing, high temperature steam activation and refining. Its appearance is black non-stereotypes particles.
2. Advantages of product
It has the advantages of advanced pore structure, large specific surface area, strong adsorption ability, high mechanical strength, small beds resistance small, good chemical stability, easy regeneration, durability and etc. and has all kinds of granularity.

4. Usage
Nut shell activated carbon is widely used for deep purification of drinking water, industrial water, wastewater, domestic water and gas adsorption, such as water quality purification in the industries of power plant, petrochemical, refinery, food and beverage, sugar, wine, pharmaceutical, electronic, pisciculture, seaborne. It can effectively adsorb the free chlorine, phenol, sulphur and other organic pollution especially the precursor substances that cause mutations, which can achieve purification, deodorization, and removing impurities, It is also can be used for industrial tail gas purification, gas sweetening, oil catalytic reforming, gas separation, pressure swing adsorption, air drying, food stored, gas mask, solution vectors carrier, industrial solvent filtering, decolorization, purification, all kinds of gases separation, purification, refining, organic solvent recovery, and the decolorization, deodorization, refining of sugar, monosodium, medicine, wine, beverage, heavy metal refining, and as catalyst and catalyst carrier in the chemical industry.
5. The cautions in transit:
1) In transit the activated carbon should prevent to mixed loading, not trample and tread, in case charcoal grain broken to influence the quality.
2) In transit, store, and use process should absolutely prevent flooding, because of after flooding, a significant amount of water is full of activity space to make the activated carbon lose use.
3)Prevent tar substance, should ban tar substance into carbon bed, to avoid blocking activated carbon interspace.
4) Prevent directly contract with fire in transit, to avoid firing. When activated carbon is regenerating should avoid oxygen entering, and make regeneration thoroughly. After regenerating, must use steam to cool down to 80 degrees Celsius below, otherwise high temperature and encounter oxygen can make the activated carbon ignite spontaneously.
