Char is the solid material that remains after light gases (e.g. coal gas) and tar have been driven out or released from a carbonaceous material during the initial stage of combustion, which is known as carbonization, charring, devolatilization or pyrolysis. Further stages of efficient combustion (with or without char deposits) are known as gasification reactions, ending quickly when the reversible gas phase of the water gas shift reaction is reached. WebThe acid source can be one of phosphoric acid, sulphuric acid, boric acid, and halides, as well as their derivatives; the carbonizing source mainly includes pentaerythritol (monomer, dimer, trimer), sorbitol, mannitol, dextrins, starch, phenol-formaldehyde resins, and char-forming polymers like PA-6, PU, and PC.
