In industrial chemistry, coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), methane (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for heating and ...

Conclusion. Fuel gas from gasification may be utilized for power generation after it is properly cleaned in downstream process. The clean fuel gas with high CO and H 2 content has the potential for production of liquid petroleum fuels through FischerTropsch process. However, achieving such clean fuel gas is nowadays a major concern in research.
