| Abstract | ||
| In this investigation, sulfurized granular activated carbon of good quality was prepared from Beji asphalt by mixing with about 15% by weight of concentrated sulfuric acid (H2SO4). The overall yield of granular activated carbon was 80% by weight of asphalt. The activated granules have a total surface area (air-Permeability) of 4605 cm2/g, iodine number of 965 mg/g, ash content of 5.3% maximum, hardness number of 99%, bulk density of 0.604 g/cm3, and a volume activity of 582.9 mg/l. Such properties make the produced carbon suitable for waste water treatments and other applications. | ||
