Coal Gasification

About Coal Gasification:

• It is a thermo-chemical process that converts coal into syngas.
  • A synthetic gas composed mainly of carbon monoxide (CO), hydrogen (H₂), carbon dioxide (CO₂), methane (CH₄), and water vapour (H₂O).
  • Coal is reacted at high temperatures (1000–1400°C) with a controlled amount of oxygen and steam, producing syngas.
• Process of Coal Gasification:
  • Preparation: Coal is finely crushed to increase surface area.
  • Gasification reactor: The powdered coal is fed into a reactor with limited oxygen/air and steam.
  • Chemical reactions: Coal breaks down into syngas components due to partial oxidation.
  • Gas cleaning: Impurities like tar, sulfur, and dust are removed from raw syngas.
• Benefits of coal Gasification:
  • Coal gasification can help address local pollution problems.
  • It is considered a cleaner option compared to the burning of coal.
  • It will help in reducing reliance on imports of natural gas, methanol, ammonia and other essential product.
  • It has the potential to alleviate the environmental burden by reducing carbon emissions and fostering sustainable practices.
