The pores of wood based activated carbon Activated carbon can be produced from many carbon-containing materials, with the most common including coal, wood and coconut shell. The source material can greatly impact the properties of the resulting activated carbons.For example, activated carbons from d

the classification of active carbonactive carbon are complex products which are difficult to classify on the basis of their behaviour, surface characteristics and other fundamental criteria. However, some broad classification is made for general purposes based on their size, preparation methods, and
