Roughly divided powdered activated charcoal air purification carbon coconut shell activated carbon coal columnar activated carbon powdered activated carbon is activated carbon 1. Appearance husk pore structure is refined and sawdust have developed a non-toxic black fine powder tasteless with stable large surface area and strong adsorption capacity, high purity filtration rate quality and so is mainly applied to a variety of amino acid industry bleaching refined sugar decolorization MSG industry glucose industrial starch sugar industry chemical additives dye intermediates food additives drugs of high pigment solution 2. deodorant purification purify air purification activated carbon air purification Activated carbon is the most widely used effect most mature safest and most reliable kind of absorbing material in a way most of activated carbon as an excellent physical and chemical sorbents more and more people's attention 3. The use of high-quality coconut shell activated carbon coconut shell activated carbon coconut shell as raw material is refined shape for the amorphous particles having a short black product impurities developed pore structure adsorption fast adsorption rate cycle low surface cleanliness good wear resistance, high strength edges rounded size Repeated use of renewable uniform features coconut shell activated carbon is mainly used in food and beverage Pharmaceutical air purification and high purity drinking alcoholic deodorant and liquid chlorine removal of heavy metals from water and can be widely used in bleaching solvent recovery and gas separation in the chemical industry and other 4 . shell activated carbon shell with quality apricot shell walnut shell peach shell as raw materials after carbonization activation from finishing the appearance of black granular products with reasonable pore structure developed strong adsorption capacity and high specific surface area pore distribution easy regeneration Economy durable 5. coal columnar activated carbon coal columnar activated carbon developed porosity has large surface area and good adsorption properties excellent chemical stability and mechanical strength, heat-resistant acid is widely used in chemical metallurgy and textile Environmental Defense Daily living in such areas as scientific and technological progress and improving people's living standards and more extensive use of activated carbon
