✓Correct Answer
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.
