Olive stones have been carbonized under a flow of nitogen in the temperature range from 700 to 900°C and activated in a CO2 flow in the range from 675 to 875°C. ZnCI, was used in some of the activation processes. The adsoptive characteristics of the carbonized and activated samples have been determ
## Abstract The polymeric precursor polystyrene sulphonate beads were used to produce activated carbon spheres (ACSs). ACSs were prepared by carbonization of polymeric precursor at 800°C followed by activation of resultant char with steam and carbon dioxide activation processes. The resulting ACSs
