Granular activated carbons are made from rigid raw materials, giving the necessary hardness to avoid excessive losses due to attrition and handling. They present large internal surface of pore structure, ensuring high adsorption power in specific purposes and uses. They are used in fixed or moving beds as columns where the liquid or gas passes through and gets purified. They can be used in liquid or gas phase continous adsorption process and offer unusual economy in cases where carbon regeneration is favorable. In liquid phase applications they remove colloids and organic substances that give undesirable odors, colors and taste to the products. They are efficiently used for water dechlorination in processes which require super chlorination as well as the removal of organic substances from the water. In vapor phase application they participate in the solvent recovery, adsorption of colors, purification of carbon di-oxide and catalyst support. They are also used to reduce the COD and BOD in effluent waste water.
Granular activated carbon is produced from coconut shell charcoal by the process of steam activation. The coconut shell charcoal is fed into the rotary kiln and activated by steam at high temperatures resulting in the evaporation of impurities and opening up of pores on the surface. The resultant big particles are then crushed and sieved to get the desired particle size.
Our main grades of granular activated carbon are given as under. We can customize the iodine value as well as the particle size according to your requirements

Ammonia is a colourless gas (99.9% concentrated) with a strong characteristic odour. It is available in gaseous form and boils at -34C. In a liquid state, ammonia has to be transported under pressure or in a refrigerated state. The molecular formular is NH3. Ammonia contains about 82% nitrogen. Ammonia reacts strongly with acids to produce salts: Nitric acid into ammonium nitrate, sulphuric acid into ammonium sulphate, phosphoric acid into ammonium phosphates and hydrochloric acid into ammonium chloride.

Ammonia or azane is a compound of nitrogen and hydrogen with the formula nh3. It is a colourless gas with a characteristic pungent smell. Ammonia contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Ammonia, either directly or indirectly, is also a building-block for the synthesis of many pharmaceuticals and is used in many commercial cleaning products. Although in wide use, ammonia is both caustic and hazardous. The global production of ammonia for 2012 is anticipated to be 198 million tonnes, a 35% increase over the estimated 2006 global output of 146.5 million tonnes.Ammonia, as used commercially, is often called anhydrous ammonia. Household ammonia is a solution of nh3 in water (i.E., ammonium hydroxide) used as a general purpose cleaner for many surfaces. Because ammonia results in a relatively streak-free shine, one of its most common uses is to clean glass, porcelain and stainless steel. It is also frequently used for cleaning ovens and soaking items to loosen baked-on grime. Household ammonia ranges in concentration by weight from 5 to 10% ammonia.Because of ammonia's vaporization properties, it is a useful refrigerant. At standard temperature and pressure, ammonia is less dense than atmosphere, and has approximately 60% of the lifting power of hydrogen or helium. Ammonia has sometimes been used to fill weather balloons as a lifting gas.
HS code 2814200010
Physical and Chemical Properties
Ammonium hydroxide, also called Aqua Ammonia, solution of ammonia gas in water, a common commercial form of ammonia. It is a colourless liquid with a strong characteristic odour. In concentrated form, ammonium hydroxide can cause burns on contact with the skin; ordinary household ammonia, used as a cleanser, is dilute ammonium hydroxide.
Application
1. Agricultural use: Diluted in agriculture, it can be used as fertilizer. The ammonia concentration of agricultural ammonia water is generally controlled within the range of 15% to 18% nitrogen content, and the carbonization degree is preferably greater than 100%. Fertilization is simple and there are many methods, such as ditch application, surface application, application with irrigation water or spraying.
2. Industrial use: Used in industries such as wool spinning, silk, printing and dyeing to wash wool, woolen fabric, grey fabric, dissolve and adjust pH, and as a dyeing aid. The organic industry is used as an aminating agent, a catalyst for the production of thermosetting phenolic resins, and the inorganic industry is used for the preparation of various iron salts.
3. In industry, it is used for large-scale integrated circuit decompression or plasma CVD to grow silica film as a pH regulator for boiler feedwater. Ammonia is used to neutralize carbon dioxide in feedwater, increase pH, and slow down the corrosion of carbon dioxide in feedwater. It is also a protective agent for boiler shutdown, and has a good protective effect on boilers that have a small amount of stored water that cannot be discharged.
4. In medicine, dilute ammonia water is used to stimulate respiration and circulation, treat fainting and fainting, and be used as a skin irritant and disinfectant.
5. Used as a detergent, neutralizer, and alkaloid leaching agent. It is also used in the pharmaceutical industry, gauze industry, printing, etc.
1. Used as good solvents on a variety of polymers such as polyethylene, polyvinyl chloride, pan, polyamide, etc. It can be used for acrylic fiber and other synthetic fibers of wet spinning, polyurethane synthesis;
2. Used in the plastic film;
3. Used for catalysts for chemical reactions;
4. Used as a gas absorber for separation and purification of gases in petrochemical industry.
5. Used to remove paint; it can also dissolve some of the low solubility of the pigment, so that the characteristics of dyes with dyes;
6. Used in pesticide industry. It can be used for synthesis of iodine amine pyrimidine, doxycycline, cortisone, vitamin B6,antitumor ammonia acid, furosemide fluorouracil, bile dimension he, etc.
