The significance of tire disposal, an attractive waste to convert into burning oil or absorber etc., has been increasing day by day. However, if it does not change into a useful form, it will damage the nature and the living things. Thus, pyrolysis, a well-known method, which is used to convert recycle tire waste into gas, liquid and char. On the other hand, the waste pyrolysis oil or waste tire oil (WTO) has a substantial avaliable calorific value similar to those of fossil fuels. Due to pyrolysis reaction, high amount of sulfur is detected in the WTO; therefore, another step of explosion applied to WTO to decrease sulfur and also re-upgrade quality of oil with such catalysts as Calcium Oxide (CaO) and Natural Zeolite (NZ) at a ratio from 2 to 10 with an increase of 2 for each step, individually. It is noticed that distillation test is a key analysis for separation discrimination of rich or lean quality fuel. As a consequence of mixture of catalyst-WTO reactions, the best curve was observed at a 10% CaO-WTO mixture which was close to diesel#2 and the mixture was separated into two new fuels as light (Gasoline Like Fuel or abbreviated as GLF) and heavy one (Diesel Like Fuel or shortened as DLF) due to temperature differences. According to distillation, FT-IR, NMR and UV-vis were used to analyze WTO, GLF and DLF for defining their characterization as well. Thus, the characterization result data of samples have quasi-equivalent with standard petroleum in open literature, and can be combusted in engine as well.

“…The samples were weighed at 1.00 ± 0.01 mg by using electronic balance and triplicated each time, which was dried in an oven at 500°C for 1 h and cooled to room temperature, the weight loss before and after drying was moisture; which was dried in a muffle furnace https://doi.org/10.37358/RC.21.3.8436 at 500°C for 1 h, heat at 900°C for 3 h, and cool to room temperature, the weight of the remaining sample in the crucible was the weight of ash; which was heated in a muffle furnace at 930°C for 7 min, and cooled to room temperature in a desiccator, the weight loss before and after heating was the weight of volatiles and moisture. Fixed carbon (FC) was calculated by the formula (1) [7].…”

The rapid development of the automotive industry has led to the accumulation of a large number of waste tires that contain a lot of reusable energy. Macromolecular organics in waste tires can be crack small molecule organics via pyrolysis. In this experiment, thermogravimetry (TG) and pyrolizer-gas chromatography/mass spectrometry (PY-GC/MS) were used to study the pyrolysis behavior of waste tires with different particle sizes, and the effect of temperature and particle size on the pyrolysis products of waste tires under low-temperature pyrolysis conditions, respectively. The volatile substances in waste tires decomposed intensively at 300-500�C and were completely pyrolyzed at 500�C. The content of limonene in the pyrolysis product was significant, and the yield of limonene could reach 27.73% when the waste tire particles were 0.180-0.250 mm and the pyrolysis temperature was 380�C. The mechanism of limonene formation from waste tires was discussed. This study indicated that raw material particle sizes and pyrolysis temperature could change the components and content of pyrolysis products.

“…It was heated at a rate of 10 • C/min until reaching a maximum temperature of 950 • C with a zero holding time to avoid an enhanced carbon gasification that could remove carbon atoms and widen micropores [25]. A temperature of at least 500 • C is required during waste tire pyrolysis to ensure a complete thermal decomposition [4]; however, we use a higher temperature with the aim of causing a turbostratic structure formation, since higher temperatures are used to align graphitic layers [46]. During the whole procedure, a nitrogen flow of 200 mL/min (21 • C, 1 atm) was supplied.…”

“…During tire manufacturing, rubber compounds are processed. Additives, such as sulfur and other chemicals, are added to render a crosslinked structure that enhances some physical properties of the final product, such as durability, wear resistance, abrasion and weathering resistance, and mechanical properties [4][5][6]. These properties make them desirable as tires, but also complicate their disposal and cause environmental pollution problems if they are not correctly handled and disposed of [4].…”

Pyrolysis is a feasible solution for environmental problems related to the inadequate disposal of waste tires, as it leads to the recovery of pyrolytic products such as carbon black, liquid fuels and gases. The characteristics of pyrolytic carbon black can be enhanced through chemical activation in order to produce the required properties for its application. In the search to make the waste tire pyrolysis process profitable, new applications of the pyrolytic solid products have been explored, such as for the fabrication of energy-storage devices and precursor in the synthesis of nanomaterials. In this study, waste tires powder was chemically activated using acid (H2SO4) and/or alkali (KOH) to recover pyrolytic carbon black with different characteristics. H2SO4 removed surface impurities more thoroughly, improving the carbon black’s surface area, while KOH increased its oxygen content, which improved the carbon black’s stability in water suspension. Pyrolytic carbon black was fully characterized by elemental analysis, inductively coupled plasma–optical emission spectrometry (ICP-OES), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, X-ray diffraction (XRD), N2 adsorption/desorption, scanning electron microscopy–energy-dispersive X-ray spectroscopy (SEM-EDS), dynamic light scattering (DLS), and ζ potential measurement. In addition, the pyrolytic carbon black was used to explore its feasibility as a precursor for the synthesis of carbon dots; synthesized carbon dots were analyzed preliminarily by SEM and with a fluorescence microplate reader, revealing differences in their morphology and fluorescence intensity. The results presented in this study demonstrate the effect of the activating agent on pyrolytic carbon black from waste tires and provide evidence of the feasibility of using waste tires for the synthesis of nanomaterials such as carbon dots.
