Specification :

Apricot activated carbon uses high quality kernel as raw material, and is produced by the best productive technology. The product has strong adsorption capacity and does not have the soluble organic or inorganic matters, which have no-harmful to health. It is widely used for corp and domestic water purifiers, water dispenser, the water treatment of power plant, petrochemical industry, and is also used for the water treatment of factory, hotel, all kinds of beverage in the city with drinking water heavily polluted.

Activated carbon is a porous material containing carbon, which has highly advanced pore texture and is a excellent adsorbent, per gram of activated carbon adsorption area as much as the equivalent of eight tennis courts. The adsorption of activated carbon is reached by physical adsorption force and chemical adsorption force, besides carbon which contains a little hydrogen, nitrogen oxygen and ash, the structure is accumulated by carbon form six ring content. Because of six ring carbon irregular arrange, the activated carbon has the characters of microporous volume and high surface area.
Activated carbon is constituted by various carbonaceous materials, which contains wood, sawdust, coal, coke, peat, lignin, nut shell, hard nut shell, sugar cane pulp, bone, lignite, petroleum residue and etc. The coal and coconut shell have become the most commonly employed raw material to produce activated carbon. Activated carbon manufacturing basically divide into two major processes.First, include dehydration and carbonization, heating materials, drying in the temperature 170 to 600 and making the original organic carbonized about 80% .Second, it is to make carbonized content activation, which is finished through the activator of steam and carbon reaction. In the Heat-sink reaction, it is mainly produce the mixed gases composed by CO and H2 to burn Heating carbonized content to proper temperature( 800 --1000 ) , which is used to burn all biodegradable materials. So the activated carbon has advanced mesoporous molecular, large specific area and strong absorption capacity. The pore of activated carbon can divide into three types according to aperture size. Macro pore: radius 1000---1000000A Filter pore: radius 20----1000A Micro pore: radius---20A
Because of different raw material, activated carbon has different size of aperture. The coconut shell activated carbon has the smallest aperture. The wood based activated carbon usually has the biggest aperture, and is used to adsorb larger molecules and almost dedicated in liquid phase. The first type granular activated carbon is used in urban water treatment field, which is made of wood and called wood charcoal. The aperture size of coal based activated carbon is between them. In the coal based activated carbon, lignite activated carbon has more filter space and larger average pore size than anthracite activated carbon, so it can effectively remove macromolecular organic matters in water.
Usually activated carbon is used in water treatment, which does not need larger surface area, but should have more filter pore and larger average pore size.
