Abstract
Carbon materials prepared using different methods were characterized by XRD, Laser Raman and BET (Brunauer Emmett and Teller) methods. Adsorption removal of dibenzothiophene (DBT) from octane solution was performed on these carbon materials at room temperature. The adsorption was carried out in a liquid phase at room temperature. The effect of carbon surface chemistry on DBT adsorption activity was also studied. Carbon materials DBT adsorption capacities show a strong dependence on surface areas, pore size distributions and micropore volumes, and the introduction of metal species enhances their adsorption capacities somehow. However, there is a limit to the amount of metal species loaded because overloading metal species would block the pores, which leads to the decrease of adsorption capacities of the activated carbon.
