Activated carbon is a material which commonly used in air purification, mainly used to adsorb the few toxic gases, ammonia, formaldehyde and benzene without pollution,toxic and side effects.
The effect of activated carbon,Activated carbon is a black powder, granular or pelletized amorphous porous carbon, the main component of carbon, but also contains small amounts of oxygen, hydrogen, sulfur, nitrogen, chlorine. Has a large specific surface area (500 ~ 1000 m2 / g), has a strong adsorption capacity, can adsorb on its surface gas, liquid or colloidal solid; for gas, liquid, adsorbed mass quality can be close to activated carbon The quality of itself. Its adsorption is selective, and non-polar substances are more easily adsorbed than polar substances.
In the same series of substances, the higher the boiling point of the material more easily adsorbed, the greater the pressure the lower the temperature the greater the concentration, the greater the amount of adsorption. On the contrary, decompression, heating is conducive to the desorption of gas. Commonly used in gas adsorption, separation and purification, solvent recovery, sugar, grease, glycerol, drug decolorants, drinking water and deodorants in refrigerators, gas masks in the toxic agent can also be used as a catalyst or metal salt Catalyst carrier. The early production of activated carbon raw materials for wood, hard shell or animal bones, are mainly coal, carbonized, activated carbon activated carbon production methods are:
1, steam, gas activation method: the use of water vapor or carbon dioxide at 850 ~ 900 ℃ carbon activation;
2, chemical activation method: the use of activator release gas, or impregnation of raw materials with activators, can be obtained after high temperature activated carbon.
Activated carbon has a microcrystalline structure with a completely irregular arrangement of crystallites with micropores (radius less than 20Å = 10-10 m), transition pores (20-1000Å) and large pores (greater than 1000Å in radius) Large inner surface, the specific surface area of 500 ~ 1700 m2 / g.
This determines the activated carbon has good adsorption, adsorption of waste water and exhaust gas metal ions, harmful gases, organic pollutants, pigments and so on. Industrial application of activated carbon also requires mechanical strength, good wear resistance, its structure and strive to stability, adsorption energy required to facilitate regeneration. Activated carbon used in oil, beverages, food, drinking water decolorization, off-flavor, gas separation, solvent recovery and air conditioning, as a catalyst carrier and gas mask adsorbent.
