Coal gasification technology can be used in the production of ethanol and urea, but not nitroglycerine. Ethanol can be produced through coal gasification by converting coal into syngas, which can then be processed into ethanol. Urea production involves the use of coal gasification to produce ammonia, which is a key component in urea synthesis. However, nitroglycerine is not produced using coal gasification; it is typically synthesized from glycerol and nitric acid. Therefore, coal gasification technology can be used in the production of two of the listed substances: ethanol and urea.
