The main components of activated carbon are chemically divided: carbon (C) and small amounts of oxygen (O), hydrogen (H), sulfur (S), nitrogen (N), and chlorine (Cl).
The main components of activated carbon are divided by function:
For example: use of activated carbon to recover the solvent from the air containing solvent vapors; deodorize the air using activated carbon filter; used in gas masks and industrial respirator to prevent poisons. Activated carbon for air purification is very popular.
For example: recovering benzene from city gas; recovering gasoline, propane and butane from natural gas; treating waste gas from Fischer-Tropsch synthesis to recover hydrocarbons from it.
For example: in the sugar industry, the activated carbon is used to decolorize the sugar solution; in the chemical industry, the activated carbon is used to decolorize organic substances; the activated carbon is used to purify the organic impurities in the electroplating bath to ensure the quality of the electroplating surface and to remove phenol from the waste water. Another kind activated carbon for liquid adsorption is activated carbon for Water treatment.
