An amount of 1.5 billion waste tires has been generated every year, resulting in serious environmental problems and damaging human health caused by landfilling and direct burning. One of the most effective valorization processes for the waste tire is to convert it into energy. To achieve this objective, pyrolysis and hydrothermal liquefaction (HTL) as two major thermochemical conversion technologies have been widely applied for producing liquid fuel from waste tire. This produced tire oil can be either used for energy purposes but also as the precursor to synthesize valuable chemicals such as benzene, xylene, toluene, and limonene. Within this framework, this review extensively summarized the recent studies focusing on the tire oil production by pyrolysis and HTL, along with the current applications of waste tire-derived oil. In addition, the available research regarding the use of solid product obtained from pyrolysis and HTL as an alternative to activated carbon for wastewater treatment and reinforcing filler is discussed. Furthermore, future directions and the main conclusions are provided.

每年产生15亿只废轮胎，导致严重的环境问题，并由于填埋和直接燃烧而损害人类健康。废轮胎最有效的增值过程之一就是将其转化为能量。为了实现该目标，热解和水热液化（HTL）作为两种主要的热化学转化技术已被广泛应用于从废轮胎生产液体燃料。这种生产的轮胎油既可以用于能源目的，又可以用作合成有价值的化学物质（如苯，二甲苯，甲苯和li烯）的前体。在此框架内，这篇综述广泛地总结了最近的研究，这些研究侧重于通过热解和HTL生产轮胎油，以及废轮胎衍生油的当前应用。此外，讨论了有关利用热解和HTL制得的固体产物作为活性炭的替代品用于废水处理和增强填料的现有研究。此外，提供了未来的方向和主要结论。
