Its adsorption is selective, and non-polar substances are easier to be adsorbed than polar substances.In the same series of substances, the higher the boiling point of the substance, the more tolerantEasy to be adsorbed, the greater the pressure, the lower the temperature, the greater the concentration, the greater the amount of adsorption.On the contrary, decompression and heating are beneficial to gas desorption.It is often used for gas adsorption,Separation and purification, recovery of solvents,recovery activated carbon  decolorizing agents for sugar solution, grease, glycerin, medicine, deodorant for drinking water and refrigerators, filter agent for gas masks,It can also be used as a catalyst or metal salt catalyst carrier.Early production of activated carbon raw materials for wood, hard nut shell or animal bones, later mainly used coal, after dryingDistillation, activation treatment after the production of activated carbon methods are :① steam, gas activation method.Carbon is activated by water vapor or carbon dioxide at 850~900℃. pelletized activated carbon suppliers
