Carbonization an overview | ScienceDirect Topics
Carbonization. Carbonization is a process that typically heats biomass feedstock in a kiln or retort (pyrolysis) at temperatures around 400°C (generally between 300 and 900°C) in the absence of air [10,11]. The produced biochar is also known as charcoal, which is a porous, carbonenriched, grayish black solid [10].

Charcoal Coal Tar Exporter from Jamnagar
Charcoal is dark grey residue consisting of carbon, and any remaining ash, obtained by removing water and other volatile constituents from animal and vegetation substances. Charcoal is usually produced by slow pyrolysis, the heating of wood or other substances in the absence of oxygen. Charcoal is usually an impure form of carbon as it contains ash; however, sugar charcoal is among the purest ...
