1. Procedure White Charcoal And Black Charcoal
Binchotan or White charcoal is synthesized by hydrolysis of hardwoods, such as oak wood, coffee trees, eucalyptus trees … at low temperatures (∼200 – 400oC) in 120 hours, then increase temperature ∼ 1000 degrees. In the end of carbonization process, White hot charcoal is removed from the kiln and poured into a mixture of earth, sand and ash moistened.
For making black charcoal we need to burn the wood at temperatures between 400 and 700 °C, then the kiln is sealed until the burning stops and the heat slowly dies away. You can now see the surface of the charcoal is black. Black charcoal is soft and retains the outer layer of the wood.
2. Content of white and black Charcoal
|Content||White charcoal||Black Charcoal|
|Fixed Carbon (%)||93.9||71.28|
The proximate analysis summarizes the moisture content, volatile matter, fixed carbon and ash in the samples, see table above. Each of these parameters provides elements to analyse the materials performance during either combustion or other thermos-chemical process. The raw materials moisture affects not only the performance of the solid biofuels on thermo-chemical processes, but also the phenomena occurring during densification. The higher the moisture, the more energy is wasted when using the raw materials on thermo-chemical processes.
In this post ” White Charcoal – Everything you need to know“, we had mentioned about that white charcoal has a range of novel properties. So, White Charcoal is expected to be a potential candidate in the future.

The table above describes the comparison of the applicability of white coal and black coal in our lifi. Clearly, Binchotan is an optimal choice for many applications. But also note that its cost is higher than normal black charcoal.
