Activated Carbon is a kind of black powder, granular or pellet or amorphous with porous
Carbon. The main component is carbon, and contains a small amount of oxygen, hydrogen, sulfur, nitrogen and chlorine. It mainly has wood, fruit shell, coal and other high temperature activation. Carbon is the most stable element in nature, and activated carbon also has this characteristic. The pore structure is developed in activated carbon, with a large surface area (500 ~ 1000m 2/ gram), even higher, with strong physical adsorption properties, which can adsorb gas, liquid or colloidal solids. For gases and liquids, the mass of the adsorption material can be close to the quality of the activated carbon itself. Its adsorption is selective, and non-polar material is more adsorption than polar material. In the same series of substances, the higher the boiling point is, the more likely it is to be adsorbed, the higher the pressure, the lower the temperature, the higher the concentration, the greater the adsorption capacity. On the contrary, the decompression and heating are beneficial to the desorption of the gas.
Activated carbon used in gas adsorption, separation and purification, solvent recovery, liquid sugar, petroleum oil, glycerin, drugs, drinking water and refrigerator deodorant, gas masks in the filter agents, air purification, can also be used as catalyst or carrier of the metal salt catalysts, etc.
