Product Detail

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.
