Activated carbon is very important chemical has wide application and employed by numerous industries which require absorption of certain gases and vapors in purification, in catalytic chemical reactions, de colorization of vegetable oil and sugar solutions. Activated carbon manufactured from coconut shell is considered superior to those obtained from other sources mainly because of small macro pores structure which renders it more effective for the Coconut shell is used for manufacturing a variety of products of commercial importance including activated carbon. Activated carbon is a non graphite form of carbon which could be produced from any carbonaceous material such as coal, lignite, wood, paddy husk, coir pith, coconut shell, etc. adsorption of gas/vapor and for the removal of color and odor of compounds. The activated carbon is extensively used in the refining and bleaching of vegetable oils and chemical solutions, water purification, recovery of solvents and other vapors, recovery of gold, in gas masks for protection against toxic gases, in filters for providing adequate protection against war gases/nuclear fall outs, etc. Product characteristics H value - 6.5-7.5 Adsorption capacity at % by mass - 45 Moisture (max) - 5% Ash - 5% Hardness - 90 Applications • Granulated activated carbons are used for purification of gases or liquids and are used in a vertical carbon packed column • Activated carbons have been used as carriers for catalyst in the manufacture of chlorinated hydrocarbons. • Activated carbon finds application in the preparation of pills and digestive tablets. Its adsorptive properties are utilized in the treatment of laments of the stomach due to hyper acidity. • In the laboratory, it is used for the production of high vacuum, purification of gases, determination of vapor content in a carrier gas, etc. Global demand National Scenario In India activated carbon industry is of recent origin. There were only one or two manufacturing units in early fifties which have now increased to 50 or even more. But now activated carbon industry is widely spreaded in different parts of the country. Most of the units are in small scale sector. However, based upon the enquiries there are more than 50 units manufacturing activated carbon for selling. They are located in different parts of the country. Most of these units have capacity of more than 100 tonnes. Quite a few units have installed capacity of more than 1,000 tonnes also. Only 10 to 12 units cater to the national market, all other units cater by and large to local or regional market. It is learnt that the total installed capacity of present available was about 75,000 tonnes and production was around 65,000 to 70,000 tonnes which includes purified and regenerated carbon too. International scenarios Estimated demand of activated carbon in developing countries like Bangladesh, Sri Lanka and gulf countries, where industrial development is emerging up is around 134580 MT in 2014 to 2015. The future of beverage industry is very bright. As the demand for activated carbon from this industry is likely to increase rapidly the estimated to be 15 percent annum and accordingly estimated demand are around 12790 in 2010 to 2011. Activated carbon is also being used in nuclear plants and laboratories for containment of many radioisotopes. Since the applications and demand of activated carbon is immense therefore the potential of the product is excellent. It is one of the imperative fields to endeavor.
