Coconut Based Carbon

Like its name, coconut shell activated carbon comes from the coconut shell. To create its activated carbon form, the coconut undergoes a steam activation process. During activation, it creates millions of pores at the surface of the carbon thus increasing the total surface area. Coconut shell carbon has mainly micro-pores to meso-pores and due to its unique distribution of pore diameter, coconut shell activated carbons are very popular in the gas phase purification and potable water purification industries Coconut shell-based activated carbons are the least dusty. Predominantly microporous, they are well-suited for organic chemical adsorption. Coconut shell-based carbon has the highest hardness compared to other types of activated carbons, which makes it the ideal carbon for water purification. In terms of base materials, coconut shell and wood are renewable resources. Coconut plantations with millions of acres of land continue to provide all the benefits of green trees to our environment in spite of using billions of coconut shells per year for activation. Activated carbon is produced from coconut shells in a two-step process. The first step in activation is to carbonize the shells to drive about two-thirds of the volatiles out of the shells, creating a carbonaceous mass full of tiny pores. In the second stage, this carbonized base material is activated at high temperature (1,100 °C/2,012 °F) in steam. Activation temperature and the amount of activation time are important to create the internal pore networks and to impart certain surface chemistries (functional group) inside each particle. In essence, the total activation process gives carbon its unique adsorption characteristics.
