Coal Gasification & Liquefaction

ЁЯФ╣ 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). 

ЁЯФ╣ Benefits
1. Transporting gas is a lot cheaper than transporting coal. 
2. Help address local pollution problems. 
3. Has greater efficiency than conventional coal.

ЁЯФ╣ 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.
