The temperature of the pyrolysis process can vary significantly depending on the specific type and purpose of the pyrolysis being conducted.
What is the temperature of the pyrolysis process? (4 Key Factors Explained)
1. General Temperature Range
Pyrolysis typically involves temperatures ranging from 400 to 550°C.
However, it can also be performed at lower or higher temperatures depending on the desired outcomes.
2. Lower Temperature Pyrolysis (Torrefaction)
Torrefaction, a form of pyrolysis, is conducted at temperatures between 200-300°C in the absence of oxygen.
This process involves slow heating of biomass at rates less than 50°C/min over several hours to days.
During torrefaction, water and volatile compounds such as CO, CO2, H2, and CH4 are released.
The resulting solid material retains about 70% of the mass and 90% of the energy content.
This solid material is hydrophobic and suitable for long-term storage.
3. Medium to High Temperature Pyrolysis
For processes aimed at producing bio-oil or converting waste materials like tires and plastics into oil-like substances, temperatures typically range between 600 to 700°C.
These higher temperatures are necessary for the effective decomposition of more complex organic materials.
They are often conducted under pressure.
The high temperatures ensure rapid and complete decomposition, facilitating the transformation of the feedstock into valuable products.
4. Control and Equipment Requirements
The pyrolysis reactor must be designed to accommodate these temperature ranges, ensuring efficient heat transfer and control.
For instance, in high-temperature pyrolysis, the reactor must be capable of maintaining temperatures around 500°C in the vapor phase.
It should have a short residence time for the pyrolysis vapors (less than 1 second) and rapid cooling (quenching) to preserve the quality of the bio-oil product.
