coal carbonization process

Carbonization is a pyrolytic reaction therefore is considered a complex process in which many reactions take place concurrently such as dehydrogenation condensation hydrogen transfer and isomerization Carbonization differs from coalification in that it occurs much faster due to its reaction rate being faster by many orders of magnitude For the final pyrolysis temperature the amount of heat applied controls the degree of carbonization an
