At what temperature does wood have to be heated to for pyrolysis to begin? – 4 Key Temperatures Explained

1. Initial Pyrolysis Begins at 270°C

The temperature at which wood begins to undergo pyrolysis is approximately 270°C.

At this temperature, wood starts to degrade or carbonize.

This degradation involves the breaking of chemical bonds within the wood's structure, primarily carbon-carbon bonds.

2. Intensified Pyrolysis at 400°C

As the temperature rises further to around 400°C, the pyrolytic decomposition intensifies.

This phase typically requires several hours to complete and is characterized by more extensive chemical changes.

At these higher temperatures, the wood's components break down more thoroughly, leading to the formation of various byproducts.

3. Formation of Byproducts

The byproducts of pyrolysis include bio-char, bio-gas, and other volatile compounds.

The specific products and their proportions depend on factors such as temperature, pressure, and the duration of exposure to heat.

4. Importance of Pyrolysis

Pyrolysis is critical in the conversion of wood into different forms of carbon and other chemical compounds.

These compounds can be used for various energy and material applications.
