Frequently asked some questions

What is scrap tyre?

Scrap tire refers to a tire that has exceeded its intended lifespan and is no longer suitable for its original purpose. This can include used tires, tire casings that can be reused, or various parts of a tire. Repurposing or recycling scrap tires can help reduce waste and promote sustainability.

What's the pyrolysis product ?

Pyrolysis is a thermal decomposition process that breaks down organic materials, such as scrap tires, into smaller molecules using heat in the absence of oxygen. The products of pyrolysis can vary depending on the process conditions and the feedstock material, but generally, pyrolysis of scrap tires produces the following products:

Pyrolysis Oil: This is a dark-colored liquid with a high energy content, which can be used as a fuel or a feedstock for further processing into chemicals and other products.
Pyrolysis Gas: This is a mixture of gases, including hydrogen, methane, carbon monoxide, and carbon dioxide. The gas can be used as a fuel for heating the pyrolysis reactor or can be burned to generate electricity.
Char: This is a solid residue that is left behind after the pyrolysis process. It is composed mainly of carbon and can be used as a fuel or a feedstock for further processing.

Pyrolysis of scrap tires is an effective way of producing energy and valuable products from waste materials, while also reducing the amount of waste sent to landfills.

What’s kind of systems you could provide?

Tire Collection Systems: These are systems designed to collect scrap tires from various sources such as tire dealers, repair shops, and individuals.
Tire Shredding Systems: These are systems that shred scrap tires into small pieces, which can be used as feedstock for other processes or recycled into new products.
Pyrolysis Systems: These are systems that use heat to break down scrap tires into oil, gas, and carbon black. The oil and gas can be used as fuels, while the carbon black can be used as a reinforcing filler in rubber products.
Recycling Systems: These are systems that use various processes to recycle scrap tires into new products such as rubberized asphalt, rubber mulch, and molded rubber products.
Waste-to-Energy Systems: These are systems that convert scrap tires into energy through combustion, gasification, or other processes. The energy can be used to generate electricity or heat.

What is Carbon Black?

Carbon black is a form of amorphous carbon that is produced by the incomplete combustion of hydrocarbons, such as coal tar, ethylene cracking tar, and crude oil. It is composed of small, spherical particles that have a high surface area-to-volume ratio and a very fine particle size. Carbon black is commonly used as a reinforcing filler in rubber products, such as tires, belts, hoses, and gaskets, to improve their mechanical properties, such as strength, durability, and wear resistance.

Carbon black is produced by burning hydrocarbons under controlled conditions, which involves the injection of a hydrocarbon feedstock into a high-temperature flame. The process produces a cloud of soot that is collected and then processed to remove impurities and to control the size and properties of the particles. The resulting carbon black is typically characterized by its particle size, surface area, structure, and purity, which can vary depending on the process conditions and the feedstock material.

Carbon black is also used as a pigment in inks, paints, and coatings, as well as a conductive additive in batteries, electronics, and other applications. It has a high electrical conductivity and can act as a filler to improve the mechanical and electrical properties of the material it is mixed with. Carbon black is a versatile material with a wide range of applications in various industries, including rubber, plastics, coatings, inks, and electronics.

Is It possible to pyrolysis with water containing inside raw material?

Pyrolysis of materials containing water can be challenging because the water can interfere with the pyrolysis process and affect the quality and quantity of the products produced. Water can lead to steam formation, which can cause pressure buildup and reduce the effectiveness of the pyrolysis process.

However, there are pyrolysis processes that can handle materials containing water, such as hydrothermal pyrolysis. This process uses water as a reaction medium and operates at high pressures and temperatures to promote rapid decomposition of the feedstock. The water helps to reduce the formation of char and enhance the production of liquid and gas products.

Another method is steam pyrolysis, which uses steam instead of air or other gases to promote thermal degradation of the feedstock. Steam can help to increase the heat transfer rate and promote the release of volatile products.

In summary, it is possible to pyrolyze materials containing water, but it requires specialized pyrolysis processes that can handle water-containing feedstock and minimize the negative impact of water on the pyrolysis products.

What are the applications of oil and carbon black?

Oil and carbon black are the two main products that are produced from the pyrolysis of scrap tires. Here are some of the common applications of each product:

Oil: Pyrolysis oil, also known as tire-derived fuel (TDF), is a valuable product that can be used as a fuel for boilers, furnaces, and engines. It has a high energy content and can be used as a substitute for fossil fuels, which can help to reduce greenhouse gas emissions. Pyrolysis oil can also be further refined into transportation fuels, such as gasoline, diesel, and jet fuel, or into chemicals, such as benzene, toluene, and xylene.
Carbon Black: Pyrolysis also produces a solid residue called carbon black. Carbon black is a valuable material that can be used as a reinforcing filler in tires, rubber products, plastics, and other applications. It can improve the strength, durability, and resistance to wear of these materials. Carbon black can also be used as a pigment in inks, paints, and coatings or as a conductive additive in batteries, electronics, and other applications.

In summary, pyrolysis oil and carbon black produced from scrap tire pyrolysis have various valuable applications in fuel, chemical, rubber, and other industries.
