Abstract

Presents study shows the effect of different activation methods to produce activated carbon from olive seeds residues. Pre-treatment of the seeds with carbonization at 400 ᵒC for 30 min. The produced char impregnate in KOH solution (1:1 ratio) for chemical activation. After that, the char was dried at 105 ᵒC for 60 min in the oven. Four different sizes (3, 4, 5, and 6 mm) of the produced char were achieved. Samples of 100 g of char were activated at four different temperature levels of (250, 350, 450 and 550 ᵒC) for activation time of (15, 20, 25 and 30 min) respectively. Four gage pressures of (atmosphere, 1.3, 1.6 and 1.9 bars) were achieved in the activation process at constant nitrogen flow rate 50 cm³/min. The results showed that there is a clear effect on the surface area of the produced activated carbon, the best value of surface area for the produced activated carbon was1091.58 m²/g at maximum iodine absorption of 1099.9 mg/g, activation temperature 450 ᵒC, activation time 25 min, practical size 3 mm and atmosphere pressure.
