Pyrolysis Flow Chart: From Origin to Final Application
As a professional pyrolysis machine manufacturer, we understand that our clients and industry partners often want to see not only the technology itself but also the bigger picture of how the process works from start to finish. That is where a pyrolysis flow chart becomes indispensable.
A well-designed flow chart clearly shows the journey of waste materials—from their origin as discarded resources, through the pyrolysis process, and finally into valuable byproducts with real-world applications. In this article, we will walk you through the complete closed-loop of the pyrolysis flow, providing insights into each stage of the process and showing how our machines make waste-to-value transformation possible.

1.What Is a Pyrolysis Flow Chart?>>>
A pyrolysis flow chart is a step-by-step diagram that outlines the transformation of waste materials under high temperatures and an oxygen-free environment. It highlights the different inputs, processing stages, outputs, and final applications.
For plant owners, investors, and operators, this flow chart is more than a graphic—it is a tool to:
- Understand the technology structure.
- Identify how each byproduct is collected and reused.
- Evaluate the efficiency and profitability of a plant.
- See the closed-loop nature of the process, where waste is transformed rather than discarded.
2.Production Process Flow Chart Of Pyrolysis Equipment>>>
3.Where Does the Pyrolysis Flow Begin?>>>
The flow begins with raw material input. Typical feedstocks include:
- End-of-life tires (rich in hydrocarbons and steel)
- Waste plastics (PE, PP, PS, ABS, etc.)
- Rubber products
- Oil sludge
- Biomass residues (such as nutshells, rice husks, and sawdust)
Each type of material follows the same principle: heating without oxygen causes thermal decomposition. However, different feedstocks require specific pre-treatment.
Pre-treatment of Raw Materials
Before pyrolysis, feedstocks are prepared:
- Shredding and cutting: Tires and plastics must be reduced in size.
- Drying: Wet materials are dried to ensure efficient pyrolysis.
- Sorting: Non-recyclable or harmful materials are removed.
- This ensures smoother feeding into the pyrolysis reactor and higher oil yield.
4.How Does the Pyrolysis Process Work?>>>
At the heart of the flow chart is the pyrolysis reactor.
Stage 1: Feeding System
Prepared materials are loaded into the reactor through an automated feeding system. For batch-type machines, manual feeding may be required, while continuous pyrolysis plants use conveyor or hydraulic feeding for efficiency.
Stage 2: Heating and Thermal Cracking
Inside the reactor, the feedstock is gradually heated to around 350–450°C. In the absence of oxygen, no combustion occurs; instead, the material undergoes thermal cracking, breaking down long-chain hydrocarbons into smaller molecules.
Stage 3: Formation of Byproducts
During pyrolysis, four main products are generated:
Pyrolysis Oil (Liquid Fuel) – about 35–45% yield from tires, 45–55% from plastics.
Carbon Black (Solid Residue) – about 30–35% yield from tires.
Steel Wire – about 12–15% yield from tires.
Non-condensable Gas (Syngas) – 8–12% of total yield, used to fuel the reactor itself.
Stage 4: Gas Cleaning and Condensation
The vapors released from the reactor are directed into a cooling and condensing system. Here, condensable vapors turn into liquid oil, while the non-condensable gas is separated and reused as heating fuel.
Stage 5: Discharging of Solids
Carbon black and steel wire remain inside the reactor after pyrolysis. With advanced discharging systems, these residues are removed safely and prepared for further processing.
5.What Happens in the Cooling and Recovery Stage?>>>
The cooling system plays a crucial role in turning hot vapors into usable fuel oil.
- Condensers: Reduce vapor temperature, forming liquid pyrolysis oil.
- Gas recycling system: Collects syngas and redirects it to burners, cutting down on external fuel use.
- Dust and smoke removal systems: Ensure compliance with emission standards.
This stage closes the loop between gas generation and gas utilization, making the plant energy-efficient.
6.How Are the Byproducts Applied in Real Life?>>>
The final stage of the pyrolysis flow chart is all about applications—how the byproducts create value in different industries.
Pyrolysis Oil
Industrial heating fuel in cement factories, glass plants, brick kilns, and boilers.
Electricity generation in heavy oil generators.
Further refining into diesel or gasoline through distillation units.
Carbon Black
Raw material in rubber products, plastics, and pigments.
Reinforcement filler for new tire manufacturing.
Upgraded into activated carbon, widely used in purification industries.
Steel Wire (from tire pyrolysis)
Recycled in steel plants to produce new steel products.
Sold as scrap metal to generate additional revenue.
Syngas
Used directly as heating fuel for the reactor, creating a self-sufficient loop.
Stored and purified for use in gas engines or turbines.
This closed loop ensures that every byproduct has a market value—nothing is wasted.
7.Why Is the Pyrolysis Flow Chart Important for Investors?>>>
For investors, the pyrolysis flow chart serves as a visual business model. It shows how raw waste enters the system, passes through different stages, and comes out as valuable commodities.
Key investor benefits include:
- Clear profitability structure – Knowing the yield rates and applications of each product.
- Sustainability assurance – Understanding how emissions are controlled and syngas reused.
- Operational transparency – Seeing the entire flow from input to output.

9.Case Example: Tire Pyrolysis Flow Chart>>>
To better illustrate, let’s take a closer look at the flow of waste tires:
- Shredding → Tires are cut into small blocks.
- Feeding → Shredded tires enter the reactor.
- Heating → At 400°C, thermal cracking begins.
- Oil vapor & syngas released → Directed to cooling units.
- Condensation → Oil collected in storage tanks.
- Gas recycling → Non-condensable gas reused for heating.
- Carbon black discharged → Sold as raw material.
- Steel wire separated → Recycled in steel plants.
This simple chart shows the complete closed loop—where nothing is wasted and every byproduct finds value.
