what are the products of plastic pyrolysis?

Facing the increasingly severe global plastic pollution, plastic pyrolysis technology, as a cutting-edge chemical recycling solution, is attracting widespread attention. It can convert waste plastics into valuable liquid fuel (pyrolysis oil), combustible gas (pyrolysis gas) and solid carbon black (pyrolysis residue) under anaerobic or hypoxic conditions, achieving the resource and energy utilization of waste plastics.

What is plastic pyrolysis?

Plastic Pyrolysis is a thermochemical transformation process. Its basic principle is that in an oxygen-free or extremely low-oxygen environment, through precisely controlled high temperatures, the macromolecular chains of plastics undergo thermal cracking and break down into smaller molecular compounds. Unlike incineration, pyrolysis is an anaerobic decomposition process, effectively avoiding the generation of harmful substances and efficiently recovering high-value fuel oil, syngas and solid products(carbon black).

The main products of plastic pyrolysis

The plastic pyrolysis process mainly produces pyrolysis oil (liquid), pyrolysis gas (non-condensing gas) and pyrolysis residue (solid carbon black).

1. Pyrolysis oil

Pyrolysis oil is the most closely watched and economically valuable liquid product in the pyrolysis process, typically accounting for 60% to 80% of the total products. Pyrolysis oil can be directly used as industrial fuel or, after refining, as a basic chemical raw material for the petrochemical industry.

2. Pyrolysis gas (Syngas)

Pyrolysis gas (Syngas) is a non-condensable gaseous product, typically accounting for 10% to 20% of the total product. The main components include methane, ethylene, hydrogen, carbon monoxide and carbon dioxide, etc. These gases have a relatively high calorific value and can be used as fuel for the pyrolysis process itself, reducing external energy consumption.

3. Pyrolysis residue (Carbon black)

Pyrolysis residue is the solid product after pyrolysis, usually accounting for 20% to 30% of the total product, and its main component is carbon black. High-quality carbon black can be used as a reinforcing agent or colorant for rubber products, inks and coatings. After activation treatment, it can also be transformed into activated carbon and used for water treatment and air purification.

The key factors influencing the composition and yield of pyrolysis products

The types, proportions and qualities of pyrolysis products are influenced by multiple factors, including: plastic type, pyrolysis temperature, catalyst and pyrolysis reactor design. Huayin Company has fully taken these factors into account in the plastic pyrolysis machine design to ensure that users can adjust the process parameters according to their needs and achieve the best output.
