Analysis of Tire Pyrolysis Oil

Pyrolysis technology generates TPO through the recycling of end-of-life tires (ELT). At SUNRISE, the results of the pyrolysis process are: recovered tire oil, recovered Carbon Black, recovered steel, and recovered gas.

End-of-life tires (ELT) pose a challenge due to their durable and robust tire materials. Pyrolysis offers a solution to recycle ELT by using a thermochemical process. In this process, we heat tire crumbs resulting from tire shredding to 550°C in an environment devoid of oxygen. The intricate polymers in the used tires decompose. This happens through a combination of thermal and chemical reactions. The decomposition yields oils, carbon black, and gas.

SUNRISE is one of the few factories in China that delivers electronic waste recycling equipment to the world. Our headquarter(YOTO Group) was established in 2013. Experienced SUNRISE has strict control over the pyrolysis process and strives to recycle 100% of ELT.

Following desulfurization, we can blend recycled TPO with diesel fuel. This makes it function as a substitute for fossil fuels in motor vehicles, diesel burners, generators, and construction machinery. We derive TPO from recycled scrap tires. It contributes to the EU’s goal of achieving climate neutrality by 2050. Many people have chosen to use TPO produced by pyrolysis to replace first-generation biofuels.

Because recycled TPO’s properties are similar to those of diesel, we can use the same pipelines in industrial environments to directly replace diesel with it as a heat source. TPO has applications in industrial settings, including its use for heating in processes like boiler heating.

Furthermore, the gross calorific value of TPO is impressive. This makes it a cost – effective alternative to coal or natural gas in power generation.
TPO possesses comparable energy levels to conventional fossil fuel oil, exceeding coal by 25-50% and wood by 100-200%.
Many nations rely on imported fossil fuels for electricity and heating needs. While all countries have vehicles and generate end-of-life tires (ELT), the recycling rates in numerous countries remain low. By converting ELT into TPO, these nations can decrease their dependence on imported fossil fuels.

After we distill the tire pyrolysis oil in the distillation machine, we can separate it into different components, and these components can be used to produce a variety of high – value chemicals.

Light hydrocarbons: We can separate the light part of the pyrolysis oil into light hydrocarbons such as ethylene and propylene during the distillation process. These compounds are important raw materials for the production of plastics, synthetic rubber and other chemical products.

Aromatic hydrocarbons: We can use the aromatic hydrocarbons (like benzene, toluene, xylene, etc.) in the distilled pyrolysis oil to produce chemicals such as phenol and caprolactam. People widely use these chemicals in the pharmaceutical, fragrance and dye industries.

Carbon Black Production: We can use the remaining heavy fractions to produce carbon black. Carbon black is widely used in industries such as rubber products, plastics, inks and coatings. Currently, for the majority of virgin carbon black (vCB) production, we rely on fossil fuel feedstocks. Approximately 90% to 95% of it comes from this source.

Solvent Production: We can use some of the fractions as industrial solvents. These solvents play an important role in the manufacture of products such as paints, coatings and cleaning agents.
