“…Results for different TPOs have shown initial and final distillation points between 69 and 150 °C and between 514 and 600 °C, respectively (Figure 7). 60,87,113 Recently, Marti ́nez et al 60 reported a relatively high distillation temperature at which 50% of TPO evaporates (T 50 ) of 243− 350 °C, thus confirming the unrefined nature of raw TPO. The TPO was produced in an industrial-scale pyrolysis plant based on the auger technology using a nonisothermal profile (750− 450 °C).…”

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.

This study investigates the effectiveness of kaolin and bentonite catalysts in improving liquid hydrocarbon yields during the pyrolysis of waste tires. Raw clay, nitric acid-treated clay, and mono- or bimetal-impregnated clay were used as catalysts in the pyrolysis of waste tire. Acid-treated kaolin produced a higher yield of liquid hydrocarbons (43.24–47%) compared to acid-treated bentonite (35.34–41.85%). This improvement in the liquid yield can be attributed to the higher specific surface area and pore diameter of the acid-treated clay in comparison to raw kaolin (39.48%) and raw bentonite (31.62%). Moreover, the use of metal-impregnated catalysts, such as Fe/kaolin and Ni/Fe/kaolin, resulted in higher liquid yields (47%) compared to the 3 M HNO3-treated kaolin catalyst (43.24%). Gas chromatography–mass spectrometry (GC-MS) analysis confirmed the presence of limonene, a crucial ingredient for commercial perfume production, in the liquid products. The calorific values of oil obtained through kaolin and bentonite catalysis were measured at 13,922 and 10,174 kcal/kg, respectively, further highlighting the potential of these catalysts in waste tire valorization.

“…The pyrolysis process can be carried out in several ways. The main distinctions in the literature are gas-solid systems, liquid-solid systems, and conducting the process under reduced pressure [5,6]. In vacuum pyrolysis, on the other hand, the reactor is heated with molten salts.…”

“…In addition, by performing simulated distillation, better fractional separation results are obtained than with atmospheric distillation. Thus, it is possible to achieve a final boiling point of about 600 • C, which indicates the presence of heavy hydrocarbon compounds in the pyrolysis oil [6]. A number of new studies are being carried out in the field of pyrolysis affecting the quality of the products obtained [8,9].…”

One method of managing used car tires is decomposition by thermochemical conversion methods. By conducting the process at temperatures of 450–750 °C, three fractions are obtained from tires: oil, gas, and solid. The liquid product of the pyrolysis of used car tires is pyrolysis oil, which consists of aromatic, polyaromatic, and aliphatic hydrocarbons. Unconventional building materials were obtained from tire pyrolysis oil and the environmental impact was evaluated. Blocks made from pyrolysis oil showed mechanical strength of up to about 1700 N. No heavy metals or polycyclic aromatic hydrocarbons, which were found in the crude heavy-PO fraction, were detected in the filtrates after incubation of the block obtained from the heavy-PO fraction at 240 °C. The highest inhibition of Sorghum saccharatum shoot (74.4%) and root (57.5%) growth was observed for solid materials from the medium-PO fraction obtained at 240 °C. The most favorable values of the parameters for the process of obtaining blocks based on post-PO were an annealing temperature of 180 °C, time of 20 h, and mass ratio of catalyst to catalyzed oil of 0.045.
