Question

What happens in the Carbonization process?
(A) Hydrolysis
(B) Electrolysis
(C) Pyrolysis
(D) All of the above.

Answer 1

Hint: The carbonization reaction takes place in the presence of heat. The heat decomposes the organic materials like plants or dead animals into its carbonaceous form.

Complete answer:
-Carbonization is the process which involves the breakdown of complex substances into simpler ones.
- It involves the conversion of the organic substance such as wood or agricultural residues into carbon or carbon-containing substance by heating or destructive distillation. Since there is involvement of heat the process is also called pyrolysis.
- Pyrolysis is defined as the thermal decomposition of the organic substances at an elevated temperature. It involves change in the chemical composition.
-Carbonization reaction is also involved in the pyrolysis of coal into coke. Carbonization and coalification are different.
- Carbonization is an exothermic process.
- The reaction can take place at a temperature around 300-400℃.
Since extreme heat is involved in this process, pyrolysis takes place in the carbonization process.

Therefore, correct answer is option(C) Pyrolysis

Additional information:
Factors which are influencing the yield in carbonization process are given below:
- Moisture content present in the wood at the time of carbonization.
- Type of carbonizing equipment used.

Note: - Carbonization process produces harmful residues and in order to reduce the risks necessary precaution should be taken.
- The smoke produced during the carbonization reaction produces very high content of carbon monoxide, which is harmful to our health. It can damage our respiratory system, so necessary care should be taken.
- The residues given out during the Carbonization process can be irritating to skin, we have to cover our body and face fully.
