Tire pyrolysis refers to the process of using high temperature to induce thermal chemical reactions of organic substances in waste tires under specific anaerobic or hypoxic conditions, resulting in the decomposition and conversion of high molecular compounds in tires into low molecular substances. Its essence is to break the chemical bonds of large molecules such as rubber in tires through heating, causing them to break down into small molecule substances. So what are the specific products of tire pyrolysis? What are the applications of these products? Let's take a look together below.
1. Refining tire oil:
It is the substance that produces the most amount of refined tire oil. Engineering tires, truck tires, etc. can produce 45% -50% refined tire oil, while small car tires, motorcycle tires, etc. can produce 35% -40% refined tire oil. It has a high calorific value, generally around 10,300 kcal, and can be used as an alternative fuel for boiler, steel plants, etc. It can also be refined to produce non-standard diesel.
2. Carbon black:
After the tire pyrolysis reaction, about 35% of carbon black will be produced. Its calorific value is around 7,000 kcal, which can be directly discharged and sold as fuel or compressed into balls for combustion. It can also be refined and ground into powder as raw materials for rubber, pigments, etc.
3. Exhaust gas:
During the process of tire pyrolysis, 5% -15% of exhaust gas is produced, mainly composed of methane, which has high combustion value and is generally used as fuel to supply tire pyrolysis heating equipment to reduce costs.
4. Steel wire:
It is a substance used in tire production, and its properties and state remain basically unchanged after pyrolysis reaction. It can be pulled out by machine and accounts for about 10% -12% of the composition of pyrolysis products. Steel wire can be directly recycled and sold, or re-melted and cast for processing new products.
In addition, from a microscopic perspective, the gases produced by pyrolysis may also include ethane, ethylene, propylene, carbon monoxide, benzene, toluene, aromatic compounds, etc.
