Among its numerous sources, coconut shells have gained significant attention as a sustainable and efficient raw material for producing high-quality activated carbon. Coconut shell-based steam-activated Carbon is mainly used for the removal of chlorine, organic contaminants, color and odor from drinking water to make it suitable for human consumption. Being microporous in internal structure, coconut shell activated carbon is well suited for organic chemical adsorption, including volatile organic chemicals.
- One of the prominent applications of coconut shell-based activated carbon is in water treatment processes. It effectively removes impurities, organic contaminants, and heavy metals, ensuring clean and safe drinking water.
- It acts as a decolorizing agent, removing impurities and unwanted odors from edible oils, beverages, and food products finding its application in the food and beverage industry. Additionally, it is employed in the purification of sugar syrups, ensuring high-quality and clear syrup for various confectionery and beverage manufacturing processes.
- It serves as an excellent adsorbent in the production of drugs, where it eliminates unwanted impurities, colorants, and traces of heavy metals making it ideal choice in pharmaceutical industry too. The high purity and porosity of coconut shell-based activated carbon make it a preferred choice for pharmaceutical manufacturers to ensure product quality and safety.
Wood Based Powder Activated Carbon is used for decolorizing in sugar liquors, juices,soybean and food industries. Wood powder activated carbon is non-toxic, without taste and it has the appearance of a fine black powder.
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
Black activated carbon is a highly porous and adsorptive material commonly produced from carbon-rich materials such as coconut shells, coal, or wood. It is widely used in water treatment, air purification, and industrial processes due to its exceptional ability to remove impurities, toxins, and odors. Activated carbon works by trapping chemicals and contaminants within its vast network of pores, making it highly effective in filtering and purifying liquids and gases.
In addition to environmental applications, it is used in food and beverage industries for decolorizing liquids, in pharmaceuticals for toxin removal, and in chemical processing for gas purification. Its versatility extends to personal care products, where it is used for detoxifying and cleansing purposes in skincare.
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 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.
