Carbonization
The carbonization of wood in an industrial setting usually requires a temperature above 280 °C (536 °F), which frees up energy and hence this reaction is said to be exothermic.This carbonization, which can also be seen as a spontaneous breakdown of the wood, continues until only the carbonised residue called charcoal remains. Unless further …
