Granular activated carbon

 Granular activated carbon is a porous material containing carbon, it has a highly developed pore structure, is a very good adsorbent, granular activated carbon adsorption area per gram equivalent of eight tennis and drinking places much more, while its adsorption is by physical adsorption and chemical adsorption reached its component substances in addition to carbon elements, still contain small amounts of hydrogen, nitrogen, oxygen and ash, the formation of six carbon ring structure was made of material accumulation. The six ring carbon irregular arrangement, resulting in a microporous activated carbon particles characteristic size and high surface area.

Second, the classification of granular activated carbon

Granular activated carbon material in accordance with distinction generally be divided into wooden granular activated carbon, and coal quality granular activated carbon, granular activated carbon made of high quality wood coconut, peach shell, apricot shell as raw materials; coal quality granular activated carbon of high quality anthracite as raw materials. Activated carbon adsorption is a measure of the quality standards, while the size of adsorption and activated carbon has a surface area of a relationship, it is the largest in terms of surface area is powdered activated carbon, powdered activated carbon adsorption although very good, but because it is in powder form, in the course of easily lost, so the market is more commonly used granular activated carbon.

Third, the use of granular activated carbon

No matter what kind of granular activated carbon material is the use of advanced technology refined processing, the appearance of a black cylindrical particles, granular activated carbon with a reasonable pore structure, good adsorption properties, high mechanical strength, easy to repeated regeneration, and low cost. QUALITY granular activated carbon Mainly used toxic gas purification, gas processing, industrial and domestic water purification, solvent recovery and so on. Granular activated carbon is mainly used for wood: mainly used for deep purification of drinking water, pure water, beverage, wine, industrial water, power plants, sewage and water quality to bleaching.
