Coal Gasification
Context:
• Government has initiated steps to execute the four pilot coal gasification projects.
What is Coal Gasification?
• Coal gasification is a process in which coal is partially oxidised with air, oxygen, steam or carbon dioxide to form a fuel gas.
• This gas is then used instead of piped natural gas, methane and others for deriving energy.
• In-situ gasification of coal – or Underground Coal Gasification (UCG) – is the technique of converting coal into gas while it is still in the seam and then extracting it through wells.
• Production of Syngas: It produces Syngas which is a mixture consisting primarily of methane (CH4), carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2) and water vapour (H2O).
• Syngas can be used to produce a wide range of fertilizers, fuels, solvent and synthetic materials.
