QQuestion

Consider the following substances :
I. Ethanol
II. Nitroglycerine
III. Urea
Coal gasification technology can be used in the production of how many of them?

OOptions

A
A) Only one
B
B) Only two
C
C) All the three
D
D) None

Correct Answer

B) Only two

DDalvoy Solutions

Coal gasification technology can be used in the production of two of the mentioned substances:

I. Ethanol: Yes, coal gasification produces syngas (synthesis gas) which can be converted to ethanol through the Fischer-Tropsch process or other catalytic processes.

II. Nitroglycerin: No, nitroglycerin is typically produced from glycerol and nitric acid through nitration processes, not from coal gasification products.

III. Urea: Yes, coal gasification produces hydrogen and carbon monoxide, which can be further processed to produce ammonia. Urea is then synthesized from ammonia and carbon dioxide, making it possible to produce urea from coal gasification derivatives.

Therefore, ethanol and urea can be produced using coal gasification technology.

SUPSC Prelims Strategy and Tips

For industrial chemistry questions, focus on the primary products of the given process (in this case, syngas from coal gasification) and trace which final products can be derived from these intermediates through known chemical pathways.
