Active carbon spheres were prepared by chemical activation using acid-pretreated resin beads, composed of sulfonated polystyrene divinylbenzene. Carbonization and activation were carried out simultaneously at various temperature ranges from 200 to 900 Β°C for 4 h, under gentle fluidization conditions

## Abstract The polymeric precursor polystyrene sulphonate beads were used to produce activated carbon spheres (ACSs). ACSs were prepared by carbonization of polymeric precursor at 800Β°C followed by activation of resultant char with steam and carbon dioxide activation processes. The resulting ACSs
Activated carbon was prepared from chickpea husk by chemical activation with K 2 CO 3 . At 1073 K, the specific surface area of activated carbon prepared with an impregnation ratio of 1.0 yielded the maximum value of 1778 m 2 /g. From the results of the yield of the activated carbon and the reagent
