hiilitetään
Hiilitetään is a Finnish term that translates to "carbonize" or "charring" in English. It refers to the process of converting organic materials into carbon or carbon-rich residues through pyrolysis or destructive distillation. This typically occurs when organic matter is heated in the absence of oxygen. During hiilitetään, volatile components are driven off, leaving behind a solid, carbonaceous material. Common materials subjected to this process include wood, peat, and agricultural waste. The resulting product, charcoal, has been used for millennia for various purposes, including fuel, metallurgy, and as a soil amendment. The specific temperature and duration of the process influence the properties of the final carbonized product. In industrial contexts, hiilitetään can be a key step in producing activated carbon, which has a highly porous structure and is used in filtration and purification processes. It is a fundamental process in understanding the transformation of biomass.
