Abstract

Waste tire pyrolysis has emerged as a promising thermochemical conversion technology for recovering valuable liquid fuels while addressing the environmental challenges associated with end-of-life tires. For this purpose, tire-derived fuel was pyrolyzed in a fixed-bed reactor at varying temperatures of 560 °C, 565 °C, 580 °C, 590 °C, and 600 °C. The maximum pyrolytic oil yield was achieved at 600 °C, producing approximately 45.56% liquid, 22.44% gas, and 32% solid residue. Increasing the temperature improved oil yield while reducing gas output. The physicochemical properties analyzed for the pyrolytic oil include calorific value, viscosity, density, flash point, fire point, and elemental composition. Fourier Transform Infrared Spectroscopy (FT-IR) analysis revealed various functional groups, including alkanes, alkenes, aromatics, and carbonyl compounds, indicating a complex hydrocarbon mixture. Thus, this study aims to produce tire pyrolysis oil (TPO) and assess its suitability as an alternative fuel for IC engines through yield analysis and fuel property characterization.
