Salt-Catalyzed Activation of Olive-Seed Waste Residue Using Fluidized-Bed Reactor
Activation of olive-seed waste residue was carried out under nitrogen atmosphere in a fluidized-bed reactor system. Initially, the starting materials were impregnated with two different salts. The salts were zinc chloride (ZnCl2) and potassium chloride (KCl). The effects of some process variables on both yield and quality of the prepared products were studied. Adsorption quality was measured in terms of adsorptive capacity towards methylene blue dye and iodine number. The effects of impregnation ratio, activation temperature, time, and particle size on adsorption quality were investigated. In general, it was found that ZnCl2 was more effective than KCl. Overall, higher activation temperature, longer activation time and smaller particle size produced a higher quality activated carbon. The produced materials were compared to a physically prepared activated carbon. They were comparable and found to be more superior.
