Coal gasification is a thermochemical process in which heat and pressure break down coal into its basic chemical constituents. The resulting "syngas" is comprised primarily of carbon monoxide and hydrogen, and occasionally other gaseous compounds. Syngas can be used for electricity production, used in energyefficient fuel cell technology ...

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.

Underground Coal Gasification (UCG) takes advantage of the same chemical reactions of coal to produce product gases, as those occurring in conventional gasifier reactors. The main difference is that in UCG the underground coal seam itself becomes the reactor, so that the gasification of the coal takes place underground instead of in a manufactured gasification vessel at the Obviously ...
