What is the Process of Co-Pyrolysis? (4 Key Steps Explained)

Co-pyrolysis is a process that involves the simultaneous pyrolysis of two or more types of feedstock under controlled conditions.

This process is conducted in the absence of oxygen to prevent combustion and to optimize the yield and quality of the products.

4 Key Steps of Co-Pyrolysis

What is the Process of Co-Pyrolysis? (4 Key Steps Explained)

1. Preparation of Raw Materials

The feedstocks are prepared by grinding, sorting, or cleaning to ensure uniformity and optimal reactivity during pyrolysis.

Proper preparation is crucial as it affects the efficiency and product quality of the pyrolysis process.

2. Drying

The feedstocks are dried to remove moisture, enhancing the efficiency of the pyrolysis process and preventing the reactor from functioning as a simple water boiler.

Drying is typically carried out to achieve a moisture content of no more than 15%.

3. Pyrolysis

The dried feedstocks are subjected to high temperatures (typically 400-800°C) in an oxygen-free environment.

This thermal decomposition breaks down the organic material into volatile gases, liquid products, and solid char.

The specific conditions (temperature, pressure, and heating rate) can be adjusted to favor the production of certain products.

4. Condensation and Collection

The volatile products are condensed and collected, while the non-condensable gases and solid char are also gathered for further use or processing.

The condensable fraction typically includes bio-oil, while the non-condensable gases can be used as fuel or for other chemical processes.

The solid char can also be collected and used as a fuel source or in other applications such as soil amendment.
