High quality coconut shell activated carbon coconut shell raw material to produce high quality activated carbon, it is a kind of irregular particles broken carbon, high strength, for repeated regeneration after saturation, high adsorption capacity, low resistance is its distinctive features, this kind of products are widely used in fixed bed or fluidized bed, coconut shell activated carbon used in the central water purifier, drinking water, industrial water decolorization, deodorization and removal of organic matter and residual chlorine. Gas phase adsorption using granular activated carbon, coconut shell is usually let air adsorption by activated carbon layer. According to the different status of the adsorption of activated carbon layer, adsorption layer has a fixed, mobile and flow layer. But, in the refrigerator and deodorization device, such as small cars in the adsorber, rely on the convection and diffusion of the gas adsorption. In addition to the granular activated carbon, activated carbon fiber and activated carbon molding are also day by day the widespread application in the gas phase adsorption.
