Waste plastic to oil pyrolysis process
1.Plastic Pyrolysis Process Principle
Plastic pyrolysis is the thermal decomposition of plastic waste at different temperatures (280–400°C) in the absence of oxygen, to produce liquid fuel oil(pyrolysis). It involves the molecular breakdown of larger plastic molecules into smaller molecules of oil gas and carbon by using heat.

2.Plastic Pyrolysis to Oil Process Steps
Plastic pyrolysis is a process that involves the thermal decomposition of plastic waste to produce fuel or other valuable products. Here are the general steps involved in plastic to fuel oil pyrolysis process:

A. Waste Plastic Pretreatment
Drying: remove moisture content and improve the pyrolysis efficiency.
Shredding: If you adopt semi-continuous type or fully automatic waste plastic pyrolysis machine, waste plastic waste should be shredded into smaller pieces to increase the surface area for better heat transfer during the subsequent pyrolysis process.
B. Heating for Pyrolysis
The dried and shredded plastic is then fed into a pyrolysis reactor, where it undergoes a thermochemical decomposition process in the absence of oxygen. The plastic is heated to high temperatures, typically ranging from 300 to 800 degrees Celsius, causing it to break down into various gaseous, liquid, and solid products.
C. Pyrolysis Oil Condensation
The gaseous products produced during pyrolysis, such as hydrocarbons and other volatile compounds, are passed through a condensation system. This system cools the gases, causing them to condense into liquid products. The condensed liquids can include pyrolysis oil, which can be further processed for various applications.
D. Exhaust Gas Purification
The exhaust gas generated in the pyrolysis and pyrolysis machine reactor heating process will go through the environmental protection devices for dedusting and filtration. This step is essential to ensure that the released gases meet environmental standards and to prevent the release of pollutants.
E. Plastic Pyrolysis Final Products Collection
The final step involves collecting the end products of the plastic to fuel oil pyrolysis process. These final products of plastic pyrolysis machine may include:
Pyrolysis oil: A liquid fuel that can be used for heating or as a feedstock for producing non-standard diesel
Syn-gas: The uncondensable gas generated in plastic pyrolysis process---syngas may be utilized for heating plastic pyrolysis machine reactor to save energy investment.
Carbon black: The remaining solid material after pyrolysis has applications as a carbon source or for other uses.

4.Plastic waste materials selection for pyrolysis process:
Pyrolysis technology can convert a variety of plastic waste into resources such as fuel oil, such as PE, PP, PS, ABS, household plastic waste, medical waste plastic, domestic plastic waste, paper mill waste, etc., but not all plastics(except PVC and PET plastic). Different plastics have different yields of pyrolysis products. When applying it, factors such as plastic type, pyrolysis machine configuration design and product processing capacity need to be considered.

5.Plastic Pyrolysis Plant Purchase Scheme
Executing the plastic to oil pyrolysis process requires a specialized production line – waste plastic pyrolysis machine. This waste plastic to oil recycling machine consists of feeding system, pyrolysis reactor, combustors, oil gas condensation system, exhaust purification system, etc. The detailed configurations of waste plastic pyrolysis machines for different customers' requirements are different.
