What happens to the feedstock during pyrolysis? 5 Key Transformations

During pyrolysis, the feedstock undergoes several significant transformations.

5 Key Transformations

What happens to the feedstock during pyrolysis? 5 Key Transformations

1. Drying the Feedstock

First, the feedstock is dried to remove any moisture present in the material.

This is necessary to ensure efficient pyrolysis and prevent unwanted reactions.

2. High-Temperature Pyrolysis

After drying, the feedstock is subjected to high temperatures ranging from 400 to 800 degrees Celsius (752 to 1472 degrees Fahrenheit) in the absence of oxygen.

This process is known as pyrolysis.

3. Formation of Solid Biochar

During pyrolysis, the organic material in the feedstock undergoes thermal decomposition and breaks down into three phases: solid biochar, liquid bio-oil, and syngas.

The solid biochar is a fine-grained residue with a high carbon content.

It is formed by the thermal decomposition of biomass in the absence of oxygen.

Biochar can be used as a soil amendment or for other purposes.

4. Production of Liquid Bio-Oil

The liquid bio-oil is produced through the condensation of volatile gases generated during pyrolysis.

This liquid can be further refined for various applications.

5. Generation of Syngas

Syngas, which is a mixture of combustible gases, is also produced during pyrolysis.

This gas mixture can be used as a source of energy.
