Silcarbon - Powdered, Granular and Pelletized Carbon - Brochure

Activated carbon is a porous carbonaceous material with a very high (internal) surface area. The manufacturing of activated carbon from non porous charcoal is called activation. During this process a large number of pores of various sizes is generated by interaction of steam and carbon dioxide with the raw material at high temperatures (700-900°C). The structure of the remaining carbon-framework depends on the type of raw material, which characterizes the pore size distribution as well as the mechanical stength of the activated carbon. Therefore a very hard raw material, like coconut shells, makes a very hard and abrasion resistant activated carbon. Silcarbon activated carbons are mainly manufactured from coconut shells. However, Silcarbon also supplies activated carbons made from charcoal (wood) or coal as alternatives for special applications.
