Preparation Of Sulfurized Granular Activated Carbon From Beji Asphalt Using Concentrated H2so4

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.
