What' the tyre oil extraction rate? How to improve it?

In the rapidly growing field of waste tyre recycling pyrolysis, understanding the tyre oil extraction rate is essential for businesses aiming to maximize profitability and efficiency. The tyre oil extraction rate refers to the efficiency with which oil can be extracted from waste tyres through pyrolysis. Typically, the yield of oil from tyre pyrolysis ranges from about 30% to 55% of the tyre's weight, depending on several factors including the type of tyres, their composition, and the specific conditions used in the pyrolysis process. This passage will introduce you in details.

Factors Affecting Tyre Oil Extraction Rate

Tyre Composition: Different types of tyres have varying compositions, affecting the amount of oil that can be extracted. For example, tyres with a higher proportion of natural and synthetic rubber tend to produce more oil. All kinds of rubber sheets or carpets have an oil extraction rate of 30%; unclassified rubbers, rubber cable sheath and rubber soles have an oil extraction rate of 35%; motorcycle and bicycle tyres have an oil extraction rate of 35%-40%; Large vehicle tyres, such as those from trucks and buses, have an oil extraction rate of 45% - 52%.

Pyrolysis Temperature: The temperature at which pyrolysis occurs significantly impacts the oil yield. Optimal temperatures typically range between 400°C and 500°C. Too low temperatures may result in incomplete conversion, while too high temperatures might promote gas production over oil. The most suitable temperature for tyre pyrolysis is around 280-320°C.

Heating Rate and Residence Time: Rapid heating rates and appropriate residence times ensure efficient breakdown of tyre materials into oil, char, and gases. Fine-tuning these parameters can enhance oil yields.

Reactor Design: Efficient reactor designs that provide uniform heating and good contact between the tyre material and heat source contribute to better oil extraction rates.

How to Improve Tyre Oil Extraction Rate

Optimize Pyrolysis Conditions: Adjusting the temperature, heating rate, and residence time based on the tyre type and desired product distribution can lead to improved oil yields. DOING provides intelligent PLC control system, This system precisely monitors and adjusts the pyrolysis temperature, pressure, and other parameters in real - time, optimizing the extraction process for maximum oil yield.

Improve Reactor Efficiency: Upgrading to more advanced reactor systems designed for optimal heat transfer and material processing can increase oil extraction rates. DOING waste tyre pyrolysis reactors are made of national standard materials and can be customized with stainless steel for a longer service life.

Pre-treatment of Tyres: Shredding tyres into smaller pieces before pyrolysis increases the surface area exposed to heat, potentially leading to higher oil yields. DOING provides you with pretreatment equipment, such as steel wire drawing machines, tyre shredder, tyre baler, tyre steel wire circle cutter, tyre cut-off machine and rubber powder processing equipment.

To improve the tyre oil extraction rate, in addition to choosing the right type of waste tyres, investing in high - quality pyrolysis equipment like DOING is crucial. DOING provides comprehensive after - sales services, including installation, training, and maintenance, ensuring that customers can use the equipment smoothly and efficiently.
