Abstract

   Co-pyrolysis of waste tires (WT) and date seeds (DS) in a batch-vertical reactor under an inert atmosphere was accomplished to produce pyrolytic chat (PC), which was employed in producing activated carbon (AC) by the optimized method with KOH. The operating circumstances for the KOH-activation route were optimized, such as the ratio of KOH: PC, temperature of activation (500 - 900 °C), and period of activation (30 to 150 min). Impregnating the PC with 2:1 KOH: PC with activation at 700 °C for 1h produced the best AC sample. The latter was identified for its     FESEM, XRD, BET surface area, EDX, and pore volume, and the outcomes showed that it possessed 371.56 m2/g surface area with a 3.81nm mean pore diameter, signifying its mesoporosity. Stripping DBT form model gasoline (200 ppm DBT/hexane) besides purifying polluted water from 200 ppm Erichrome Black T (EBT) dye were achieved by the as-synthesized AC. A removal efficiency of 95.45 % employing 0.30 g of AC at 25 °C for 30 min was achieved with model gasoline, while stripping EBT from the contaminated water amounted to 98.97 % at 25 °C for 60 min with 0.20 g of the AC. Finally, the AC showed a reasonable  reusability for several cycles with a considerable efficiency.
