Activated Carbon is made from carbonaceous source materials such as coconuts, coal and wood which is later refined by highly advanced technology. The main component used to create it is any natural product with a high carbon content. It is produced to achieve a large internal surface which makes it ideal for adsorption and can be combined with certain chemicals in order to enhance its properties.
The carbon material should have pore sizes that are larger than the material that it is adsorbing. The molecules that are removed will be held in the carbon’s pore structure. This adsorption process will aid the carbon in reducing toxic gases, activate chemical reactions and a carrier of biomass and chemicals.
As previously mentioned, it is an excellent adsorbent made for purifying air, water, gases and controlling odour, the Activated Carbon is a cost-effective way to treat a high volume of gas or water that has a low contaminant concentration due to its large surface area of 800 to 1,200 m² per gram.
- Gas purification
The activated carbon are usually used in compressed air and gas purification to remove hydrocarbons from the air. The large charcoal beds adsorb these gases and retain them as they rapidly decay, the solids are trapped in the charcoal particles while the filtered air passes through.
- Chemical purification
It is used to purify solutions of organic molecules containing unwanted impurities. Large scale chemical and pharmaceutical processes uses filtration over the carbon as well for the same purpose. The carbon is mixed with the solution then filtered off or with the filter.
It has many applications in removing pollutants from air and water streams both on the field and in industrial processes such as air purification and drinking water filtration. It is effective in water treatment as carbon is multi-functional in nature.
