Coal Gasification & Liquefaction

🔹 Coal Gasification: The process of producing syngas, a mixture consisting carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), natural gas (CH4), and water vapour (H2O). 

🔹 Benefits

1. Transporting gas is a lot cheaper than transporting coal. 

2. Help address local pollution problems. 

3. Has greater efficiency than conventional coal.

🔹 Coal Liquefaction: an alternative route to produce diesel and gasoline and makes economic sense only in a world of high crude oil prices. 

1. liquefied coal emits twice as much CO2 as burning oil. It also emits a large volume of SO2.
