Question

Define carbonization.

Answer 1

Hint: Carbonization is the conversion by thermal decomposition of organic matter such as plants and dead animal remains into carbon.This generally works in the anaerobic condition or in the presence of limited amounts of oxygen or other substrates, catalysts or solvents for the processing of organic matter.

Complete step by step answer:
-Carbonization is a pyrolysis process in which many reactions, such as , condensation, hydrogen transfer and isomerization, take place simultaneously.
-Carbonization is different from coalification, because its reaction rate is much faster.
-The amount of heat applied controls the extent of carbonization and the residual content of various elements for the final pyrolysis temperature.
-Carbonization is mostly exothermic.
-Biomaterial under searing heat can be carbonized extremely fast, and forming solid carbon.

Additional information:
Let’s discuss about wood is transformed into charcoal:
-The carbonization of wood typically requires a temperature above \[{\text{28}}{{\text{0}}^{\text{o}}}{\text{C}}\] in an industrial environment, which releases energy, so this reaction is seen to be exothermic.
-As long as the carbonised residue remains, which is known as charcoal, this carbonization continues. As the temperature reaches a maximum of \[{\text{40}}{{\text{0}}^{\text{o}}}{\text{C}}\], the system stops. -It produces appreciable amounts of charcoal.
-Carbonization involves the coke making process which is a Multistep process and a variety of products are also formed in three different states but which contains a valuable product.

Note:
To create a new catalyst for the generation of biodiesel from ethanol and fatty acids, carbonization was used. The carbonization process is mainly used to produce charcoal from the biomass.
