Catalytic Dewaxing Technology: Improve Production Efficiency by 200%
Catalytic System: Function Mechanism & Benefits
Catalytic dewaxing targets the “undesirable” molecules in pyrolysis oil distillates, that is, those with poor cold flow properties (the wax oil). Under the action of a specialized catalyst, the long-chain wax molecules are cracked into shorter-chain hydrocarbons, such as alkanes and alkenes. This modifies the molecular structure and properties of the wax. This helps to get the best pyrolysis oil performance. Finally, it brings such advantages:
- Better oil quality and higher yield: Able to produce plastic pyrolysis oil meeting ISCC certification.
- Safer pyrolysis reaction: Minimize the pressure risk of plastic pyrolysis machine by reducing wax oil blocking.
- Less downtime, fewer losses: Keeps your machine running smoothly, with improved equipment lifespan and maintenance intervals.

Get 3 Distinct Oil Products from Plastic Pyrolysis Plant to Apply
Plastic pyrolysis is the mechanism of thermally degrading long-chain plastic molecules into smaller molecules (oil, gas and char) using heat in an oxygen-free environment. Its process conditions and additional refining techniques determine the type of oil product obtained. Here’s how distinct oil products can be derived:
Naphtha / Naphtha from Non-condensable Gas
Source: pyrolysis+ distillation
Property: A low-boiling-point fraction, a light hydrocarbon product separated from pyrolysis oil.
Applications:
- produce basic chemicals (e.g., ethylene, propylene → plastics, synthetic fibers);
- used in paints, coatings, cleaners, and industrial solvents;
- used to blend gasoline for better performance;
- used to produce kerosene, jet fuel, and other fuels;
- used as an extraction solvent and cleaning agent in labs.
Non-Standard Diesel
Source: pyrolysis+ distillation
Property: A middle distillate hydrocarbon fraction from pyrolysis oil, heavier than naphtha.
Applications:
- as a kind of industrial fuel to replace traditional fuel oil;
- used as fuel for diesel generators for power generation;
- serve as fuel in ships, construction, or agricultural machinery where emission standards are less strict.
Catalytic Pyrolysis Oil
Source: catalytic pyrolysis
Property: A purer oil with fewer impurities than the common uncatalyzed waxy pyrolysis oil.
Applications:
- fuel for energy-intensive industries such as boiler plants, cement factories, and brick-making plants;
- serve as a kind of chemical feedstock for producing petrochemicals and intermediates (e.g., used to produce ethylene monomers for new plastics).
Are All Plastic Suitable for Plastic Pyrolysis Equipment?
Acceptable Plastic Types
| Types of Plastic | Coming from | |
|---|---|---|
 |
Low-Density Polyethylene | Cling films, freshness protection bags, etc. |
 |
High-Density Polyethylene | Plastic pallets, trash cans, etc. |
 |
Polypropylene | Microwave lunch box, fresh-keeping box, etc. |
 |
Polystyrene | Fast food box, bowl of instant noodles, etc. |
 |
Other Plastics without chlorine and oxygen | Various sources |
Note: PP, PE, and PS plastics are highly recommended for pyrolysis due to their high oil yield of 80%-95%. They offer great economic recovery value.
Unacceptable Plastic Types
| Types of Plastic | Coming from | |
|---|---|---|
 |
Polyethylene Terephthalate | Mineral water bottles, carbonated beverage bottles, etc. |
 |
Polyvinyl Chloride | Raincoat, building materials, etc. |
|
Other plastics with chlorine and oxygen | Various sources |
Note: Plastics containing high amounts of oxygen(O) and chlorine(Cl) are not suitable for pyrolysis. These two substances pose risks to plastic pyrolysis machine, air quality, and worker safety.
Polyvinyl Chloride (PVC)
- Contains chlorine, which releases harmful HCl gas during plastic pyrolysis process. HCl gas corrodes equipment, harms the environment, and poses health risks to workers.
- Even if PVC pyrolysis yields oil, the oil still contains chlorine (Cl). When burned, it can release dioxins—highly toxic and carcinogenic compounds.
Polyethylene Terephthalate (PET)
- PET yields little to no oil through pyrolysis. The resulting products are mostly low-quality, powdery residues with little economic value.
- PET(chemical formula (C₁₀H₈O₄)ₙ) releases oxygen in pyrolysis. The oxygen reacts with combustible pyrolysis gas, leading to explosive risks.

From Plastic to Pyrolysis Oil: Macromolecules vs Micromolecules
Plastics: Macromolecules
Plastics are composed of long-chain macromolecules (polymers) formed by the polymerization of numerous small molecules (monomers). For example:
Polyethylene (PE): During polymerization, the double bond in ethylene monomers (C₂H₄) breaks open, and links with the double bonds of other ethylene monomers to form long chains (-CH₂-CH₂-). PE is represented as: [-CH₂-CH₂-]ₙ, where ‘n’ indicates repetition multiple times. PE often consists of thousands to millions of ethylene units.
Plastic Pyrolysis Oil: Small Molecules
Pyrolysis oil mainly consists of smaller hydrocarbon compounds, typically alkanes, alkenes, and minor aromatic compounds. For example:
PE pyrolysis: The long polymer chains break apart into shorter carbon chains, producing molecules such as:
- Alkanes (Ethane C₂H₆, Propane C₃H₈, Butane C₄H₁₀, etc.).
- Alkenes (Ethylene C₂H₄, Propylene C₃H₆, Butylene C₄H₈, etc.).
Free Radical Reactions in Plastic Pyrolysis Process
Taking polyethylene (PE) as an example, its decomposition from macromolecules to micromolecules proceeds through the following steps:
- Chain Scission Generates Free Radicals: The long polyethylene chain (–CH₂–CH₂–CH₂–CH₂–CH₂–….) first breaks during pyrolysis to generate CH₂• free radicals. Example: CH₂-CH₂ → CH₂• + •CH₂
- Free Radical Recombination: These free radicals are highly active at high temperatures and can undergo recombination reactions. For example, two CH₂• free radicals might combine to form an ethylene (C₂H₄) molecule: CH₂• + •CH₂ → C₂H₄
- Formation of Propylene: Sometimes, the CH₂• free radical might react with the cracked monomers or smaller molecules. For example, two ethylene (C₂H₄) molecules might react to form propylene (C₃H₆): C₂H₄ + CH₂• → C₃H₆
Through successive scission and recombination, the final pyrolysis oil which consists of different small molecules (C₂H₄, C₃H₆, etc.) is formed.
How Plastic Pyrolysis Plant Work？- Plastic Pyrolysis Process
01 Pretreatment and Feeding
Raw materials need to be processed into different sizes for feeding. Different feeding sizes for your reference:
- BLL-30: Work in continuous mode. Feed size diameter is less than 20mm. Feed plastic by screw feeder.
- BLJ-16: Work in batch mode. Feed size diameter is less than 1200mm. Feed plastic by manual labor.
02 Plastic Catalysis Pyrolysis
Heat the plastic pyrolysis reactor. When the temperature reaches 180 degrees Celsius, gas oil begins to generate. A significant amount of gas oil appears at temperatures between 280-350 degrees Celsius.
After the oil gas enter the catalytic tower, it reacts with the catalyst. This step mitigates issues related to wax deposition and liquefaction. Simultaneously, it contributes to enhancing the quality of the plastic pyrolysis oil.
03 Plastic Pyrolysis Oil Collection
The oil gas enters the manifold, and heavy particles of the oil gas will be liquefied and dropped into the heavy oil tank. The light oil gas will be liquefied into fuel oil by the condenser and stored in the fuel oil tank.
04 Combustible Gas and Solid Residues Recycling
The non-liquefiable oil gas will be desulfurated and cleaned in the hydro seal. Then it is recycled to the burning room to provide heat energy for plastic pyrolysis equipment.
The water-cooling discharger will discharge the solid residues.
05 Emission Gas Recycling
