What is coconut shell based activated carbon?
Coconut shell activated carbon is made from high-quality coconut shell through a series of production processes. Its appearance is black and granular. It has the advantages of developed pores, good adsorption performance, high strength, easy regeneration, economy and durability. Coconut shell activated carbon is mainly used for purification, decolorization, dechlorination and deodorization of drinking water, purified water, wine making, beverage and industrial sewage; It can also be used for mercaptan removal in oil refining industry.
The majority of the world's coconut shell origin mainly come from Sri Lanka, including raw materials sourcing and activation process. Coconut activated carbon can reach very high degrees of purity. Production includes a superheating process called pyrolysis where shells are transformed into char followed by a fluidization processes in a FBR (fluidized bed reactor) where the carbon is steam activated.
Various types, sizes and performance characteristics can be targeted by carefully selected raw material, activation temperature, activation time and by varying the concentration of the oxidation gases. Following steam activation, the carbon can be sorted into different granular sizes using different mesh sizes.
Production of carbon can also generate valuable bi-products such as syngas and bio-oil.
