What is Pyrolysis of Plastic?

Waste plastics are basically made of olefins in petroleum through polymerization reactions. They are solid macromolecular materials with strong plasticity. Their chemical name is polyolefin, and their molecular weight is generally about 10,000.

The principle of waste plastic pyrolysis is to break the chain of polyolefin macromolecules and crack them into very small molecules under high temperatures and oxygen-free or oxygen-deficient conditions. Among these small molecules, C5H12-C11H24, etc. are gasoline components, and C12H26-C20H42 are diesel components. You can also understand that the pyrolysis of waste plastics is “where it came from and where it went back to”.

Analysis of Raw Materials for Plastic Pyrolysis

There are many types of plastic. However, not all plastics are suitable for pyrolytic processing. The following is a detailed explanation of the materials suitable for plastic pyrolysis.

What Kind of Waste Plastics Can be Used in Pyrolysis?

The raw materials to be processed in pyrolysis system are broadly classified into single plastics and mixed plastics.

For single plastic pyrolysis, you can mainly choose from PP, PS, HDPE and LPDE.

For pyrolysis of mixed plastics, you’d better choose PP, PS, HDPE and LPDE mainly.

You’d better not pyrolysis PET and PVC. Because the pyrolysis of PVC produces HCI, it will corrode the plastic pyrolysis equipment. Pyrolysis of PET will generate O2 and cause burning.

Waste Plastic - PP
Waste Plastic - PS
Waste Plastic - abs
Waste Plastic - LDPE
Waste Plastic - HDPE

Which Plastic is the Best Choice for Pyrolysis?

According to the results of many tests conducted by Beston engineers at the factory, PE has the highest oil yield, followed by PP/PS, ABS, and other plastics. Exactly, the oil yield of PE is as high as 95%, and the oil yield of PP/PS is about 90%. Here are details about the oil yields of different kinds of waste plastics.

Types of PlasticComing FromOil Yield
PE (Polyethylene)Beverage crates, barrels, bottles and vials, buckets, bowls, etc.95%
PP (Polypropylene)Packaging bags, wire drawing, packaging, daily necessities, toys, etc.90%
PS (General Purpose Polystyrene)Lampshades, instrument covers, toys, etc.90%

End Products of Plastic Pyrolysis – Pyrolysis Oil and Carbon Black

The products of plastic pyrolysis mainly include pyrolysis oil and carbon black. These two products have wide applications.

Main Uses of Plastic Oil

  1. Sold as fuel to cement plants, glass plants, ceramic plants, power plants, steel plants, boiler plants, etc.
  2. After further processing obtain non-standard diesel oil.
  3. Used for heavy oil generators to generate electricity.

Main Uses of Carbon Black

  1. Made of spherical carbon black and carbon black briquettes for heating and combustion.
  2. Grind to N220, N330, N550, or N6660 for the tire manufacturing industry.
  3. Processed into masterbatch and sold to the plastics industry.

As we know, this pyrolysis plant can also manage waste tire, rubber, oil sludge, and other solid wastes, while waste plastic is the raw material with the highest oil yield.

Waste Plastic Pyrolysis Process – How to Make Plastic Pyrolysis Oil?

Feeding Waste Plastic

The waste plastic is fed into the pyrolysis reactor by the screw feeder, which generally takes about 2 hours. According to the moisture content of the plastic, it is mainly divided into two feeding methods:

Dry plastic: it can be directly fed, and the door can be closed for heating after filling;

Wet plastic: It needs to be heated while feeding, first remove the water contained in the plastic, and then seal the door and start heating until it is full.

Heat the Plastic Pyrolysis Reactor

The spray gun heats the reaction kettle. When the temperature rises to the set temperature, the cracking process starts, which takes about 8-10 hours. Generally, oil and gas will be produced when it is heated for 2 hours.

Cooling to Get Plastic Pyrolysis Oil

The cooling system condenses the oil and gas into oil.

Recycle Hot Flue

In the process of plastic thermal cracking, in addition to oil and gas, there will also be some combustible but non-condensable gases, which we call “tail gas”, which can be directly recycled for thermal cracking reactors to save fuel.

Collect Carbon Black

When the pyrolysis process is over and the oil and gas are exhausted, it is necessary to discharge the residual materials in the reactor to carry out a new cracking process. These residual materials are mainly carbon black.
