The production process of activated carbon can be divided into two procedures: carbonization and activation. Carbonization is a process in which the material is turned into porous carbon structure through pyrolysisunder conditions of lacking oxygen and between temperatures from 300-500. During this process most non-carbon elements like oxyhydrogen will be eliminated as volatile gas. The combination of carbon atom-aromatic foliated structurewill have cracks because of its irregularity and these cracks will form more complicated holes when activated
Theory: Activated carbon is to oxidize coconut shells, charcoal, wood or coal into particles with many holes under high temperatures. The hole is wide on the surface while become narrower as it deepens. It is about several angstrom to thousands of angstrom in width. Every one 1kg activated carbon has hole area totaling 1,500 square meter. These holes are the only access for activated carbon to adsorb chemicals and organic matters.
