“…In addition, the TPG became richer in CH 4 and H 2 as the temperature increased in the reactor, as shown in Fig. 5a and b, which supports the occurrence of secondary cracking reactions as temperature increases during the process (Pan et al, 2021). For the CTTs, these two gases accounted for 35.7% and 53.6% of the total species at 500 • C and 600 • C, respectively, and increased from 59.4% to 69.1% at TT and HT, respectively.…”

“…Although an increasing temperature profile has not previously been studied, these results can be considered to be in agreement with the bibliography when ELT pyrolysis is conducted at different isothermal conditions. In this respect, authors as Pan et al (2021) and Arabiourrutia et al (2007) also stated that at temperatures above 600 • C, secondary reactions involving the decomposition of limonene, such as cracking reactions and further aromatisation to form monocyclic aromatics, were evident.…”

“…Significantly, the versatility of the pyrolyser plays a fundamental role (Lewandowski et al, 2019) to achieve both the technical and the economic feasibility of the process. In this respect, auger reactors are an emerging technology currently under development with a number of interesting demonstration plants for different throughputs (Campuzano et al, 2019;Choi et al, 2016;Frigo et al, 2014;Lozhechnik and Savchin, 2016;Martínez et al, 2013bMartínez et al, , 2020Pan et al, 2021). The main advantages of this technology compared to others are the low specified reactor size, low carrier gas flow rate and minimal energy requirements (Campuzano et al, 2019).…”

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