Preparation and characterization of active carbon spheres prepared by chemical activation

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 °C for 4 h, under gentle fluidization conditions facilitated with N2 flow. Effect of temperature on carbon burn-off of precursor and surface area of active carbon spheres was also studied. Prepared...
