What Does Black Charcoal Mean

Black charcoal is a type of charcoal, commonly known as soft charcoal or earth kiln charcoal. It is a highly aromatic substance produced by the pyrolysis and carbonization of fossil fuels and biomass under anaerobic conditions. The surface is pure black or wood ash with a white powder that can be blown off, so it is called black charcoal.

The composition of black carbon is influenced by the coarseness of its source (precursor biomass) raw materials, heating rate, burning temperature, etc. The main components are aromatic and aliphatic compounds, and functional groups mainly include shuttle, carbon, benzene ring, etc; Stable black carbon mainly has a cyclic structure with aromatic frameworks, as well as aliphatic chain structures.

As a fuel, black carbon has the advantages of easy ignition and low price, but it also has disadvantages such as being prone to explosion, not durable, and having smoke when burned. Moreover, the use of black carbon poses a threat to global climate, agricultural production, buildings, and even human health, so it is becoming less and less common.
