Description
Product details
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. Applications of Granular Activated Carbon : It is used in effluent treatment plant to reduce BOD / COD/ color from industrial waste water. It removes chlorine and organic impurities from drinking water in the last stage filtration in our common house hold filters. It is used as adsorbent of poisonous gases in gas masks for industrial as well as defence purposes. To adsorb moisture from compressed air in paint shops. To dechlorinate waters in swimming pool and soft drink plant. To remove oil from hot condensate. Top quality granular activated carbons are used in the process of gold recovery in which the molten ore is passed over a bed of activated carbon where the gold is adsorbed on the carbon and recovered. Used to manufacture catalyst.. Removal of dissolved organic impurities.. Breweries and distilleries. Catalyst carrier in petroleum refineries.

![Our Powder activated carbon is manufactured using pure pine wood which is an excellent base for manufacturing activated carbons with good adsorption power.
The steam activated process is done by activating the charcoal in a rotary kiln by heating at high temperatures by steam. The activated carbon that comes out from the kiln is called unwashed activated carbon. These unwashed activated carbon has higher ash and iron content. This is reduced by washing the unwashed activated carbon with acid (HCl / H2SO4) and purified water. This results in the reduction of ash content to as low as 1% and iron as low as 50 ppm.
The gradation of different qualities of activated carbon is done on the basis of Methylene blue value and iodine value. The iodine value is a better test as the particle size of iodine molecule is small enough to penetrate the smallest of pores. We can relate the iodine value of activated carbon directly to its surface area because of the above fact.
Activated carbon
Activated carbon, also called activated charcoal, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions.[1] Activated is sometimes substituted with active.
Due to its high degree of microporosity, one gram of activated carbon has a surface area in excess of 3,000 m2 (32,000 sq ft),[2] as determined by gas adsorption.[3] An activation level sufficient for useful application may be attained solely from high surface area. Further chemical treatment often enhances adsorption properties.
Given below are our standard technical specifications of our different washed and unwashed grades of steam activated carbon. You are requested to select your grade and let us know of your requirement.

Steam activated carbons are produced in a two-stage process. ...The first step is carbonization in which the raw material is burnt in the absence of air. The carbonized product is activated with steam at a temperature between 900C and 1100C. The chemical reaction between the carbon and steam takes place at the internal surface of the carbon, removing carbon from the pore walls and thereby enlarging the pores.
