Pursuing the End-of-Life Tire Circularity: An Outlook toward the Production of Secondary Raw Materials from Tire Pyrolysis Oil

Pyrolysis is perceived as the missing link between management of end-of-life tires (ELTs) and tire industry because it strikes directly in transition from a linear to circular economy model toward defossilization diverse economic sectors. Tire pyrolysis oil (TPO) one most valuable interesting fractions derived ELTs. It contains chemicals including, among others, benzene, toluene, ethylbenzene, xylene, well limonene, which are some building blocks petrochemical industry. Within framework, traditional practices such direct use TPO combustion systems seem exhibit low circularity degree. Instead, production secondary raw materials that can be reused for multiple purposes associated with getting special attention. Based on above, this work aims at reviewing different pathways currently explored scientific community produce various value-added products TPO. Due similarity its properties those petroleum streams, coprocessing using existing units conventional refineries exhibits massive potential. In manner, fine-tuned according hydrocarbons market requirements. As such, discussed advantages, recent progress, challenges implementation refinery distillation, fluid catalytic cracking (FCC), hydroprocessing, steam post-treatment. These processes seen path integrate current hydrocarbon/petrochemical market.
