The waste tire pyrolysis oil (WTPO) is getting more and more attention because of its tremendous potential. But its application is limited by the higher content of impurities and the poor fuel performance. This paper is a review of components, properties and the utilization of WTPO, to supply some novel development pathways for it. This oil mainly consisted of alkanes and aromatic hydrocarbons, while some of the impurities such as sulfide, nitride and polyaromatic hydrocarbons (PAH) were also contained in the WTPO. Besides, this oil owns poor fuel properties such as low cetane number, low flash point and high density. Blending with diesel and cleaner production (contains desulfurization and denitrification) can reduce the pollutant emissions and enhance the fuel properties of WTPO. Additionally, it is necessary to enhance the value of WTPO to increase the economy of pyrolysis. The separation and purification of limonene and the fabrication of high-quality carbon materials and pyrolysis bitumen can be regard as the high-value utilization of WTPO. In terms of techno-economic and environmental, WTPO will become a popular subject for researchers. The integrated refinery concept of WTPO deserves more attention. •The components and fuel properties of the WTPO have been summarized.•Blending with standard oil can be used to enhance the performance of WTPO and reduce the emissions.•The research of HDS and NHDS of WTPO have been reviewed.•The high-value utilization of WTPO has been extensively reviewed.
