In order to deal with the negative impacts associated with disposal of used oils by thermal remediation, a study of the material under combustion-like conditions was undertaken. Two used motor oils were subjected to slow heating using a Thermogravimetric Analyzer coupled with a Fourier Transform Infrared Spectrometer. Based on the results obtained, mechanisms of the general transformation process the oil undergoes and the evolution of the solid particles were proposed. The presence of Polycyclic Aromatic Hydrocarbons (PAHs), considered hazardous, was observed and individual PAHs were identified. The results show that initial oxygen content in the oil plays a significant role in the thermal remediation process, primarily leading to smaller, more compact final residues. This may have significant implications In terms of leachability of toxic metals. The insight gained here can be utilized in further studies to understand and then possibly control, the process in practical combustion systems.
