Coconut shell Based Columnar Activated Carbon
Coconut shell activated carbon, is a specially treated carbon that heats organic raw materials high quality coconut shell in the absence of air to reduce non-carbon components (this process is called carbonization), and then reacting with the gas, the surface is corroded to produce a microporous structure (this process is called activation). Because the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is point erosion, resulting in numerous small pores on the surface of activated carbon.
The diameter of micropores on the surface of activated carbon is mostly between 2-50nm. Even a small amount of activated carbon has a huge surface area. The surface area per gram of activated carbon is 500-1500m2. Almost all applications of activated carbon are based on this characteristic of activated carbon.
Activated carbon, in 50% w/w combination with celite, is used as stationary phase in low-pressure chromatographic separation of carbohydrates (mono-, di-, tri-saccharides) using ethanol solutions (5–50%) as mobile phase in analytical or preparative protocols.
Activated carbon is useful for extracting the direct oral anticoagulants(DOACs) such as dabigatran, apixaban, rivaroxaban and edoxaban from blood plasma samples. For this purpose it has been made into "minitablets", each containing 5 mg activated carbon for treating 1ml samples of DOAC. Since this activated carbon has no effect on blood clotting factors, heparin or most other anticoagulants this allows a plasma sample to be analyzed for abnormalities otherwise affected by the DOACs.

There are many oxygen containing functional groups on the surface of activated carbon, Activated carbon can also be impregnated with chemical substance to produce impregnated activated carbon.
We produce columnar activated carbon of different diameters, select high-quality coconut shell as the base material for treatment, carbonization and activation process, resulting in numerous small holes on the surface of activated carbon. Even a small amount of activated carbon has a huge surface area.
Thus,it is not only used as an excellent adsorbent but also used as a catalyst and catalyst carrier and widely used in industrial production ,agriculture ,environmental protection, national defence industry ,water purification ,decolorization of pharmaceutical intermediates and raw material intermediates ,air purification.etc
Application in industrial :
In industrial applications, coconut shell columnar activated carbon is used for toxic gas purification, waste gas treatment, industrial and domestic water purification treatment, solvent recovery and other aspects.
It is widely used in all aspects of industrial and agricultural production, such as alkali-free deodorization (refined sweetening), ethylene desalted water (refined fillers), catalyst carrier (palladium, platinum, rhodium, etc.), water purification and sewage treatment in the petrochemical industry; Power plant water quality treatment and protection; Chemical catalysts and carriers, gas purification, solvent recovery, decolorization and refining of oils and fats in the chemical industry;
Food industry beverage, alcohol, monosodium glutamate mother liquor and food refining, decolorization; Gold extraction and tailing recovery in the gold industry; Environmental protection industry sewage treatment, waste gas and harmful gas treatment, gas purification; And related industries of cigarette filter, wood floor moisture, odor absorption, automobile gasoline evaporation pollution control, various impregnating liquid preparation.
One major industrial application involves use of activated carbon in metal finishing for purification of electroplating solutions. For example, it is the main purification technique for removing organic impurities from bright nickel plating solutions. A variety of organic chemicals are added to plating solutions for improving their deposit qualities and for enhancing properties like brightness, smoothness, ductility, etc. Due to passage of direct current and electrolytic reactions of anodic oxidation and cathodic reduction, organic additives generate unwanted breakdown products in solution. Their excessive build up can adversely affect plating quality and physical properties of deposited metal. Activated carbon treatment removes such impurities and restores plating performance to the desired level.
Waste water treatment :
Urban drinking water, pure water, distilled water, ultra-pure water and other manufacturing equipment filling, dechlorination, oil reduction purification, all kinds of industrial sewage deep purification treatment.
Desulfurization and denitration treatment :
It is mainly used for H2S removal of biogas, water gas, semi-water gas, coke oven gas, natural gas, carbon dioxide gas, city gas, synthetic ammonia process gas, chemical raw material gas and other gases.
Formaldehyde treatment ：
Newly renovated houses more or less have formaldehyde, which seriously affects our health. The use of activated carbon and ventilated areas for treatment is a good method.
Columnar activated carbon common specifications: 1.5mm, 2.0mm, 3.0mm, 4.0mm, 5.0mm, 6.0mm, 8.0mm, 9.0mm. We are engaged in offering Coconut Shell Activated Carbon. This Coconut Shell Activated Carbon is highly demanded in the market for their excellent adsorption capacity. The application is very wide.
Chemical purification ：
Activated carbon is commonly used on the laboratory scale to purify solutions of organic molecules containing unwanted colored organic impurities. Filtration over activated carbon is used in large-scale fine chemical and pharmaceutical processes for the same purpose. The carbon is either mixed with the solution and then filtered off or immobilized in a filter.
