摘要：

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 degrees C. At 850 degrees C, the yielded activated carbon has an iodine value of 793.5 mg/g, total pore volume of 0.286 cm(3)/g and micropore volume of 0.255 cm(3)/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.
