What is Activated Carbon?
Activated carbon is a kind of microcrystalline carbon material with black appearance, developed internal pore structure, large specific surface area and strong adsorption capacity, which is a kind of commonly used adsorbent, catalyst or catalyst carrier.Activated carbon is widely used in almost all sectors of the national economy and People's Daily life, such as water purification, gold extraction, sugar decolorization, drug injection refining, blood purification, air purification, human safety protection.
Classification of activated carbon by material
Coconut shell activated carbon
Coconut shell activated carbon with high-quality nut shell or coconut shell as raw materials,It is a kind of activated carbon which is refined by the processes of carbonization, activation, superheated steam catalysis and so on. It has the advantages of good wear-resisting strength, developed voids, high adsorption performance, high strength, easy regeneration, economy and durability, etc. Mainly used for drinking water, purified water, wine, beverage, industrial sewage purification, decolorization, dechlorination, deodorization, desiccant, gold refining, catalytic carrier and other aspects.
Coal based activated carbon
Coal based activated carbon is produced through a series of processes, including carbonization, cooling, activation, washing, etc，it has the advantages of high strength, developed pores, large specific surface area and especially large volume of micropores.
According to the use can be divided into water purification, air purification, decolorization, solvent recovery, injection, protection and other purpose.Due to the acid-resistant, alkali-resistant and heat-resistant performance of coal based activated carbon, and the fact that granular activated carbon can be easily regenerated after adsorption saturation, it is an essential activated carbon adsorption material in modern industrial production and environmental protection.
Wood based activated carbon
Fruit shell and sawdust as raw materials refined but become, the appearance of black fine powder, non-toxic, tasteless, has a large specific surface area, strong adsorption ability, suitable for sugar, purification of water quality of pharmaceutical, beverage, wine industry, decolorizing, refining, purification of organic solvent and wastewater treatment are also widely used.
