The Ultimate Solution for Waste Tire Pyrolysis Equipment

Definition of Pyrolysis Technology: Pyrolysis is the ultimate treatment method for waste tires, ensuring they are fully utilized. The principle of pyrolysis involves placing waste tires, after the steel wires have been separated, in an oxygen-deficient or inert gas environment for incomplete thermal degradation, producing pyrolysis oil, non-condensable gas, and crude carbon black. The pyrolysis oil can be refined or used as fuel oil, the non-condensable gas can serve as a pyrolysis heat source, and the crude carbon black can be further processed to obtain commercially viable carbon black. This process is fundamentally different from incineration—incineration takes place in an oxygen-rich environment at 800-1000℃, producing mainly flue gas and ash, with the sole purpose of destroying the tires; while pyrolysis operates in an oxygen-free or oxygen-deficient environment (approximately 400-600℃), with the core objective of resource recycling.

Product Output and Economic Value: A waste tire pyrolysis production line with a daily processing capacity of 12 tons can produce approximately 430-450 kg of pyrolysis oil, 300 kg of carbon black, and 150 kg of steel wire per ton of waste tires. Combined with recyclable non-condensable gases, the overall net profit can reach over 500 yuan per ton. Shanxi Juyuan Renewable Resources Co., Ltd.'s comprehensive utilization project for waste tires with an annual processing capacity of 100,000 tons has a total investment of 126 million yuan. Upon reaching full production capacity, it can produce 34,000 tons of carbon black, 40,000 tons of fuel oil, and 18,000 tons of steel wire annually, and is expected to reduce carbon dioxide emissions by approximately 32,000 tons annually, equivalent to the carbon sequestration effect of planting 170,000 trees. Each tire can produce approximately 2.5 liters of pyrolysis oil and 3.5 kg of recycled carbon black. A 15-ton/day continuous pyrolysis unit can typically recover its investment within 18-24 months.

Intermittent vs. Continuous Pyrolysis Equipment: Intermittent equipment has a daily processing capacity of approximately 1-15 tons and is suitable for small businesses, experimental research and development, and scenarios with unstable raw material supply. It has relatively low investment and is simple to operate. Continuous pyrolysis equipment has a daily processing capacity of 15-50 tons or more, suitable for large-scale industrial production. It provides a more stable pyrolysis environment, resulting in more uniform product quality, a high degree of automation, and lower operating costs in the long run. Fully continuous pyrolysis units adopt an industrial assembly line operation mode, enabling stable 24-hour operation.

Environmental and resource utilization advantages: The production process operates in a closed loop. The generated pyrolysis gas is desulfurized and deodorized before being reused as fuel for reheating, forming an energy closed loop and achieving "zero emissions, zero residue, zero pollution, and full utilization." The carbon dioxide emissions from recycled carbon black can be reduced by up to 80% compared to virgin materials. An increasing number of industrial enterprises in Germany and Europe have begun using pyrolysis oil and recycled carbon black to replace fossil resources.
