Q. ‘Syngas’ is a mixture of which of the following gases?
- Carbon monoxide
- Hydrogen
- Carbon dioxide
- Methane
- Water vapour
Choose the correct answer using the codes given below:
Answer:
1, 2, 3, 4 & 5
Notes:
- Coal gasification is the process of producing syngas: a mixture consisting primarily of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), methane (CH4), and water vapour (H2O)—from coal and water, air and/or oxygen.
- Rather than burning coal directly, gasification converts all of the carbon of the coal into electricity, hydrogen, and other forms of energy through partial oxidation.
- Coal gasification can also help address local pollution problems.
- Gasification facilitates utilisation of the chemical properties of coal.
- Coal gas can be converted into chemical energy and is used for the production of iron from iron ore, as well as for the production of methanol and urea.
- Carbon Capture and Storage: another advantage of coal gasification is the fact that it lets you separate the good parts from the bad, and select the parts you want to keep.
