Abstract

Coal tar residues (CRT) are a toxic and carcinogenic waste from coal tar processing unit that need extensive post-treatment before their safe disposal. This study prepared activated carbon from coal tar residues using activating H₃PO₄ at 650-1200°C. At 850°C, the yielded activated carbon has an iodine value of 793.5mg/g, total pore volume of 0.286cm³/g and micropore volume of 0.255cm³/g, which can have feasible usage as mediate quality activated carbon. Kinetic model fitting reveals that the presence of H₃PO₄ increases effective reaction collision rate and decreases activation energy of pyrolysis reactions.
