Coconut Activated Carbon

Coconut shell carbons tend to have much higher pore volume in the microporous region and a slightly lower pore volume in the macro-porous region. This is because coconut char is less amorphous (harder, more crystalline-like) than coal. The result is that coconut based carbons adsorb smaller organic molecules, such as chloroform and other trihalomethanes (THMs), trichloroethylene (TCE), carbon tetrachloride and MTBE (methyl tertiary-butyl ether), while coal-based carbons more effectively remove larger molecules, such as color-producing compounds (tannins and humics). The predominance of micropores in coconut shell carbon gives it tight structure and provides good mechanical strength and hardness and also high resistance to resist attrition or wearing away by friction. Indocarb products are made from selected shells of coconut to ensure the highest quality during manufacturing process. Our production facility in India has the capability to carefully control particle size distribution, adsorption capacity and other critical carbon properties as required by our customers.

In addition, because of the high energy of adsorption of the coconut based carbon’s micropores, once the smaller organic molecules are adsorbed, they’re very tightly retained. Therefore, coconut shell carbons in general have a higher retentivity for these types of contaminants than do other types of carbons. For these reasons, coconut shell carbons are often selected for drinking water treatment where contamination is attributed to organic solvents or disinfection by-products such as THMs. Another advantage of coconut shell carbon is that it’s typically harder and attrition resistant than coal, lignite and peat-based carbons. This can be important in applications where attrition, carbon breakage and dust cannot be tolerated, like gold refining, gas masks and ultrapure water treatment applications.
