Oil from tyre pyrolysis as a plasticizer in rubber compounds
The paper presents the results of research on the possibility of using as plasticizers of rubber compounds the heavy fractions of pyrolytic oil obtained in the industrial process of pyrolysis of car tyres. The content of carcinogenic polycyclic aromatic hydrocarbons (PAHs) in the obtained pyrolytic plasticizers was determined.
Evaluation of Pyrolytic Oil from Scrap Tires as Plasticizer
The two oils were tested at 10 and 15 phr level in a NR-based formulation and the cure kinetics and the mechanical properties of the rubber compounds have been measured. The pyrolytic oil gives accelerated cure kinetics, reduced scorch safety and lower compound viscosity in comparison to reference compounds with DAE oil.
Oil from tyre pyrolysis as a plasticizer in rubber compounds
A number of rubber compounds and vulcanizates were prepared. The fraction of pyrolytic oil 204–450 °C was compared with commercial plasticizer Sundex 790. The obtained results showed that the compounds with pyro- lytic oil had slightly lower Mooney viscosity, and the time of optimum vulcanization was shorter.
Valorization of waste tire by pyrolysis and hydrothermal
The major components of a tire include rubber (a blend of natural and synthetic), sulfur, carbon black, oils, polymers, pigments, kinds of paraffin, fabrics, and belt materials [ 2 ]. Figure 1 shows the typical composition of tires (including passenger tire and truck tire) in North America.
Catalyzed pyrolysis of scrap tires rubber - ScienceDirect
The rubber tires samples (10 g with a granulometry 0.6–0.8 mm) are placed over the top layer of glass wool and finally covered by another layer of glass wool. The pyrolysis tests were performed under a nitrogen flow of 300 mL/min for 15 min with a residence time of 7 s.
- What is pyrolysis of rubber tyre and plastic waste mixture?
- Pyrolysis of rubber tyre and plastic wastes mixture (P) resulted in the formation of four different products namely: G (non-condensable fraction), L (light liquid fraction), HL (heavy liquid fraction) and S (solid polymer fraction) composed of lower molecular weight than the initial materials.
- How is scrap tire rubber pyrolyzed?
- Scrap tire rubber was pyrolyzed in a fixed bed reactor to produce liquid fuel. pyrolysis oil yield (50–54%) was temperature invariant in the 673–723 K range. FTIR spectra of produced oils matched those of fossil diesel. Alkali carbonate catalysts enable the pyrolysis yields to be tailored.
- Can pyrolysis convert Tire Rubber into energy?
- Pyrolysis can be used to convert tire rubber into energy, allowing for the management of such waste in the context of a circular economy. The composition and pyrolysis kinetics of granulated (0.6–0.8 mm) scrap tire rubber (TR) were assessed using thermogravimetry (TG).
- Is pyrolysis a viable method of managing scrap tires?
- pyrolysis oil yield (50–54%) was temperature invariant in the 673–723 K range. FTIR spectra of produced oils matched those of fossil diesel. Alkali carbonate catalysts enable the pyrolysis yields to be tailored. Data showed that catalyzed pyrolysis is a viable method of managing scrap tires.
- What is the pyrolysis yield of rubber tire?
- Pyrolysis yields The pyrolysis tests of rubber tire in a fixed bed reactor were carried out in a temperature range between 673 and 773 K during 15 min of reaction time under a continuous flow rate of N 2 (300 mL/min).
- Can pyrolysis be used to recycle tires?
- Every day, a huge volume of scrap tires are produced worldwide, and landfill is an ineffective method of disposing of such hazardous waste. Pyrolysis can be used to convert tire rubber into energy, allowing for the management of such waste in the context of a circular economy.
