Activated carbon black production line process

Activated carbon black component

80% to 90% activated carbon black is composed of carbon, which is hydrophobic adsorbent activated carbon as the reason. Activated carbon in addition to carbon, also contains a blend of two types: one is a chemical combination of elements, mainly oxygen and hydrogen, these elements are not completely carbonized due and remains in the charcoal, or in the activation process, foreign The non-carbon elements combined with the activated carbon surface chemistry, such as when activated with water vapor, carbon black surface is oxidized or steam oxidation; the other is a blend of ash, it is the inorganic portion of activated carbon black, some activated carbon elements. With the continuous development of activated carbon black industry, more and more industries and enterprises to use the activated carbon black, more and more companies enter into the charcoal industry.

Activated carbon black production line process

The main raw material of activated carbon black can be almost all carbon-rich organic material, such as coal, wood, shell, coconut, walnut shells, almond shells, shells and other dates. These activated carbonaceous material in a furnace at a high temperature and a certain pressure is converted to charcoal by pyrolysis plant. In this activation process, the huge surface area and pore structure of the complex formed gradually and so-called adsorption process is in these pores and on the surface of activated carbon adsorption pore size on the role of mass selective adsorption, which is Since molecules can not enter because of its pores smaller than the pore size of the activated carbon black.

Activated carbon black is a substance containing carbon as the main raw material, the high temperature carbonization and activation obtained hydrophobic adsorbent. Charcoal contains a lot of micropores, having a large specific surface area, can effectively remove color, odor, can remove two of the most organic pollutants in water and certain minerals, it contains toxic heavy metals.

Factors affecting activated carbon black adsorption  

characteristics of activated carbon black; the nature and concentration of adsorbed material; PH value of wastewater; suspended solids and other characteristics; contact system and operation methods. Activated carbon black can effectively adsorb chlorinated hydrocarbons, organophosphate and carbamate insecticides, but also adsorption diphenyl ether, n-nitro chlorobenzene, naphthalene, ethylene, xylene, phenol, DDT, aldrin, benzene sulfonic acid esters and aromatic compounds as well as many. Secondary effluent also contains organic matter not adsorbed by the activated carbon black, such as protein degradation intermediate substance adsorbed organic harder than the original charcoal, activated carbon THMS lower ability to remove only reach 23-60%. Activated carbon adsorption and other treatment methods combined with the emergence of ozone - activated carbon, coagulation - activated carbon adsorption, Habberer technology, activated carbon - diatomaceous earth method, activated carbon adsorption cycle significantly longer, reducing the amount of treatment effect and scope greatly improved.
