Consider the following substances: I. Ethanol II. Nitroglycerine III. Urea Coal gasification technology can be used in the production of how many of them?
Explanation
Coal gasification is a process that converts coal into syngas (a mixture of carbon monoxide, hydrogen, carbon dioxide, and water vapor). Syngas acts as a fundamental building block for the chemical industry.
I is correct: Syngas can be converted into Ethanol through various chemical pathways, including catalytic synthesis or fermentation.
II is incorrect: Nitroglycerine is produced through the nitration of glycerol. Glycerol is typically obtained from natural fats/oils or as a byproduct of biodiesel production, not from coal gasification.
III is correct: Coal gasification is a major source of hydrogen for producing Ammonia. This ammonia is then reacted with carbon dioxide (also a product of gasification) to produce Urea.
