The difference between White Charcoal and Black Charcoal

1. Procedure White Charcoal And Black Charcoal

White 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.

Black Charcoal:

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
White Charcoal had  fixed carbon content (93.9%), which is 22.62% larger in comparison with Black Charcoal, whereas traditional coal had more hydrogen content (5.27%) than white charcoal. Nitrogen and Sulfur are components that should be taken into account due to their capability of forming pollutants such as Nitrous and Sulfur Oxides. While nitrogen oxidation can be controlled by maintaining low reaction temperatures during combustion, sulfur reaction with air is more complicated to control. A valuable typical advantage of biomass is the low sulfur content. Binchotan had less than 0.02% sulfur, while black charcoal had 0.73% larger than 36 times.
Content White charcoal Black Charcoal
Fixed Carbon (%) 93.9 71.28
Ash (%) 2.1 8.3
Volatiles (%) 2.8 31.5
N (%) 0.22 1.63
S (%) 0.02 0.73
H (%) 0.48 5.27
O (%) 3.27 12.79

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.

3. Benefits

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.

Way to use White charcoal Black Charcoal

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.
