Activated carbon adsorption mechanism

Activated carbon adsorption mechanism:
carbon activatedcarbon is a dark abrasive, granules alternatively pellets of amorphous porous carbon, the chief makeup of carbon, also contains a small amount of oxygen, hydrogen, sulfur, nitrogen, chlorine. Also has a nice framework as graphite, merely the smaller grains, among floors of uneven collection. Has a colossal surface space (500 to 1000 m 2 / g), has a mighty adsorption in the adsorption above the surface it's gas, liquid alternatively colloidal solids; because gas, liquid, adsorption matter quality tin be close to carbon their quality. The adsorption is selective, non-polar matter is easier than the adsorption of polar substances. In the same array of substances, the higher the boiling point of the stuff more easily adsorbed, the greater the pressure the lower the temperature the greater the concentration,GHD Red Butterfly 2011, the greater the adsorption. Instead, decompression,GHD Red Straighteners, gas desorption temperature is conducive. Commonly accustom in gas adsorption, separation and purification, solvent recovery, sugar, oil, glycerin, narcotics, bleaching agents, drinking water and refrigerator deodorant, gas mask canisters in the agency, also used as catalysts or metal salts catalyst conveyor. Early creation of refreshed carbon materials as wood, hard shell or animal bones,GHD IV Mini Straighteners, and later mainly in coal,GHD Rare Straighteners, at distillation, activated carbon production acquired behind processing methods are: ① steam, gas activation usage. Use of water vapor or carbon dioxide in the 850 ~ 900 ℃ refreshed carbon. ② chemical activation method. The use of activator release of gas,GHD Diamond Flag 2011, or activator impregnated materials, tall temperature handling tin be activated.
activated carbon with a microcrystalline structure, the microcrystalline mandate totally irregular crystals in micropores (radius less than 20 [angstroms] = 10-10 m), the conversion pore (radius 20 1000), large chasm (radius 1000 100000), it has excellent interior surface, the surface area of ​​500 to 1700 m 2 / gram. This determines the activated carbon has a good adsorption, can sponge water and gas in the metal ions, toxic gases, alphabetical pollutants, colors, etc. Industrial petition of activated carbon also requires mechanical strength, wear resistance, and it sought to stabilize the structure, adsorption stamina necessitated is small, in order to facilitate regeneration. Activated carbon for oil, drinks, food, drinking water, bleaching,GHD MK4 Kiss Straighteners, de-taste, gas separation, solvent recovery and air-conditioning, and gas masks as a catalyst adsorbent.
