Are coke (solid fuel from coal) and charcoal same thing obtained
2021年8月28日 You are right in saying that coke is obtained by heating coal or oil in the absence of air while charcoal is obtained by heating wood (or other animal and plant materials) in minimal oxygen. The notable difference is the carbon %. Coke has high carbon % and less impurity % than charcoal making it a more pure carbon source.
