Activated carbon is an amorphous carbon which is black powder，granular, massive or honeycomb, it also has a regular array carbon crystal. Except the carbon, the activated carbon also contains two kinds of admixtures: one is the combination of chemical elements, mainly hydrogen and oxygen, these elements are due to incomplete carbonization and the residue in the carbon, or in the process of activation, non carbon and activated carbon surface chemical foreign combination, such as when it is activated by the water vapor , the surface of the active carbon is oxidized or water vapor oxidation; another kind of admixture is ash, it is the inorganic part of the carbon ; the ash in the activated carbon is easy to cause two pollution.
The elemental composition of activated carbon , above 80%-90% composited by carbon , which is the reason for the hydrophobic adsorption of activated carbon.
The main raw material of activated carbon can be almost all organic materials which is rich in carbon , such as coal, wood, shell, coconut shell, walnut shell, apricot shell, coconut shell etc.. The carbon material is converted into activated carbon by pyrolysis at high temperature and under certain pressure in activating oven.
The activated carbon is widely used in industrial and agricultural production, such as CAUSTIC-FREE, ethylene desalted water, catalyst carrier, water purification and sewage treatment of petrochemical industry; power plant water treatment and protection of the electric power industry; chemical industry chemical catalyst and carrier, gas purification, solvent recovery and oil decolorization, refining; food beverage industry, wine, liquor And food msgrefining, decolorization; gold extraction solution, recovery of gold industry; environmental protection industry wastewater treatment, waste gas and harmful gas treatment, gas purification; cigarette filter tipwood flooringmoisture, smoke flavor, control of automotive gasoline evaporation pollution and related industries, various impregnating agent liquid preparation etc.. Activated carbon will be an excellent development prospects and broad sales market in the future.
