Abstract: The pyrolysis of waste plastic is a kind of thermochemical treatment technology, which can not only avoid environmental pollution, but also alleviate the energy crisis. At the same time, high value-added products such as pyrolysis oil can be recovered, which has both economic benefits and environmental protection, and is the development trend of plastic recycling industry in the future. In this paper, the present status of analysis and research on pyrolysis oil of waste plastics at domestic and foreign was reviewed from the aspects of physical and chemical properties, element composition, distillation range distribution, hydrocarbon composition and non-hydrocarbon compounds. The effects of plastic type, reaction temperature, reaction time and catalyst on the properties and composition of waste plastic pyrolysis oil were introduced in detail. According to the characteristics and composition of waste plastics pyrolysis oil, the application direction of waste plastic pyrolysis oil was introduced，which provided data support for the optimization of the technology and high-value utilization of waste plastic pyrolysis oil in the future.

Key words: waste plastics, pyrolysis oil, physicochemical properties, composition
