1. Product introduction

Nut shell activated carbon with silver uses high strength nut shell as raw material, is produced by special Ag-carrying technique, and is widely used in purification equipment of water purifier, mineral spring pot, water purification machine and etc. its effect of purify water is better than ordinary water purification carbon. The activated carbon containing silver can accord to the budged effect of silver ions to sterilize and depress bacteria, and also can remove peculiar smell, odor, and small amounts of harmful material in water, after purifying the water can drink directly.

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.

 The usages of activated carbon

 Activated carbon has high efficiency air purification function, can build comfortable and clean environment, also can care for human health, it is invisible air filters. Activated carbon uses the function of physical adsorption and chemical decomposition combined can decompose harmful gases such asmethanol, ammonia, benzene, cigarettes, lampblack etc. and all kinds of unusual smell, especially carcinogenic aromatic substances. It has strong adsorption capacity, is a common adsorbent, catalyst or catalyst carrier, and can easy fully touch with harmful gases in air. Activated carbon uses own pore adsorption to adsorb the harmful gases molecular into pore, then blow out fresh and clean air. So the family partnership can’t do without activated carbon.

Activated carbon is widely used in all aspects of industrial and agricultural production, such as petrochemical industry non-alkali deodorization (refined de-mercaptan), ethylene desalination water (refined packing), catalyst carrier (platinum, palladium, rhodium and etc.), water purification and wastewater treatment, the power plant water treatment and protection in electric power industry, chemical catalyst and carrier, gas purification, solvent recovery and the decolorization and refining of oil in chemical industry, beverage, wine, MSG liquor in food industry and refining, decolorization of foodstuff, gold extraction and tail liquid recovery in gold industry, wastewater treatment, waste gas and harmful gas treatment, gas purification in environmental protection industry, and related industries cigarette filter, wood floor moisture proof, adsorbing odor, automotive gasoline evaporation of pollution control, the preparation of various impregnanting liquid and etc. Activated carbon will have a good development prospect and broad markets in the future.
