A process by which solid residues with increasing content of the element carbon are formed from organic material usually by
pyrolysis
in an inert
atmosphere.Note:
As with all pyrolytic reactions, carbonization is a complex process in which many reactions take place concurrently such as dehydrogenation, condensation, hydrogen transfer and the carbon content of the residue exceeds a more than 99 wt.% carbon is found.
As with all pyrolytic reactions, carbonization is a complex process in which many reactions take place concurrently such as dehydrogenation, condensation, hydrogen transfer and
isomerization
. It differs from coalification
in that its reaction rate is faster by many orders of magnitude. The final pyrolysis
temperature applied controls the degree of carbonization and the residual content of foreign elements, e.g. at mass fraction
of 90 wt.%, whereas at
