When the coal is heated in absence of air, it is called its ________________?
Correct answer: A. Carbonisation
- A. Carbonisation
- B. Gasification
- C. Coalification
- D. Deoxidation
Explanation
Heating coal in the absence of air decomposes it into coke, tar, gas and other products, a process called carbonisation. Gasification instead converts carbonaceous material into combustible gas using a controlled supply of oxidant.
