Consider the following substances: I. Ethanol II. Nitroglycerine III. Urea Coal gasification technology can be used in the production of how many of them?
Verified Answer
A. Only one
B. Only two
C. All the three
D. None
Explanation:
Coal gasification produces syngas (a mixture of carbon monoxide and hydrogen). Ethanol (I) can be synthesized from syngas through various catalytic processes. Urea (III) is produced from ammonia and carbon dioxide; ammonia can be synthesized from hydrogen (obtained from syngas) and nitrogen (from air) via the Haber-Bosch process. Thus, coal gasification can indirectly contribute to urea production. Nitroglycerine (II) is produced by the nitration of glycerol, a process not directly linked to coal gasification products.
