The main focus of this study was quality improvement of solid product obtained from tire-derived fuel (TDF) pyrolysis to use it as a substitute for commercial carbon blacks. First of all, TDF samples were analyzed by means of proximate and ultimate analysis, heating value, X-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis. They were then pyrolyzed at a 400 °C pyrolysis temperature with 5 °C/min heating rate. After that, a two-stage improvement was performed on solid product to reduce its sulfur and ash content to that of commercial carbon black. As a result of this improvement process, the sulfur and ash content of the solid product was reduced to 0.22 and 0.27 % from 1.71 and 12.14 %, respectively. In addition, the XRD, SEM, atomic force microscopy, Brunauer–Emmett–Teller surface area, oil adsorption number and ICP-MS/MS analyses were performed for all products. The results were compared with different commercial carbon blacks. It was determined that the properties of the improved products were similar to those of commercial carbon blacks. These results suggest that improved pyrolytic product of TDF can be used as a raw material by industries such as tire, plastic and paint manufacturing.
