Very high carbon hardwood charcoal (fixed carbon above 90%) is commonly referred to as binchotan.This type of charcoal originates from Japan and was developed during the Edo period (17th–18th century).
Fixed Carbon content over 90% can be established by using pyrolysis with temperatures 1000-1200 degr C ,in no Oxygen access media and by increasing of the exposition time.This makes the material much more expensive than the regular hardwood charcoal. One of the processes where high Carbon content hardwood charcoal can be used is metal reduction from the metal ore, for example in production of ferro alloys when there is needed high outcome of the metal.
