The end products of pyrolysis vary depending on the input material, but generally include pyrolysis oil, carbon black, steel wire (in the case of tire pyrolysis), and syngas. Pyrolysis oil is a versatile fuel or feedstock for further refinement, while carbon black is widely used in industries like rubber manufacturing, inks, and asphalt. Steel wire, recovered from tires, is recycled into new steel products. Syngas, composed of combustible gases like carbon monoxide, hydrogen, and methane, can be used for energy generation. The proportions of these products depend on the feedstock, with tires yielding 35-45% oil, 30-35% carbon black, 8-15% steel wire, and 8-15% syngas. Other materials like plastics or oil sludge may produce different ratios.

Key Points Explained:

1. Pyrolysis Oil:

   • Description: A liquid product formed during pyrolysis, often referred to as bio-oil or fuel oil.
   • Applications: Can be used directly as fuel or further refined into diesel or other chemicals.
   • Yield: Varies by feedstock; for tires, it constitutes 35-45% of the output.
   • Value Addition: High calorific value makes it suitable for energy generation or industrial use.

2. Carbon Black:

   • Description: A fine black powder, primarily composed of carbon, produced as a solid residue.
   • Applications: Used in tire manufacturing, rubber products, inks, and as an asphalt modifier.
   • Yield: Typically 30-35% of the output in tire pyrolysis.
   • Value Addition: Enhances the strength and durability of rubber products.

3. Steel Wire:

   • Description: Recovered from waste tires during pyrolysis.
   • Applications: Recycled into new steel products, such as metal abrasives or basic steel materials.
   • Yield: Represents 8-15% of the output in tire pyrolysis.
   • Value Addition: Provides a sustainable source of steel, reducing the need for virgin materials.

4. Syngas (Synthetic Gas):

   • Description: A mixture of combustible gases (e.g., carbon monoxide, hydrogen, methane) and non-combustible gases.
   • Applications: Used for energy generation or as a chemical feedstock.
   • Yield: Typically 8-15% of the output in tire pyrolysis.
   • Value Addition: Offers a clean and efficient energy source, contributing to waste-to-energy initiatives.

5. Dependence on Feedstock:

   • The composition and yield of pyrolysis products vary significantly based on the input material. For example:
     • Tires: Yield higher proportions of oil, carbon black, and steel wire.
     • Plastics: May produce more oil and less carbon black.
     • Oil Sludge: Can yield varying amounts of oil and syngas depending on its composition.

6. Environmental and Industrial Benefits:

   • Pyrolysis transforms waste materials into valuable resources, reducing landfill dependency and promoting circular economy principles.
   • The process adds significant value to common waste materials, making it an increasingly important industrial process.

7. Additional Byproducts:

   • In some cases, pyrolysis may produce other byproducts like coal fines or acid extract, depending on the feedstock and process conditions.
   • These byproducts also have industrial applications, such as in power generation or chemical manufacturing.

By understanding these key points, a purchaser of pyrolysis equipment or consumables can better evaluate the potential outputs and applications of the process, ensuring alignment with their specific needs and goals.
