Coal Gasification

About Coal Gasification:

• It is the process of producing syngas, a mixture consisting primarily of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), methane (CH4), and water vapour (H2O) - from coal and water, air and/or oxygen.
• Gasification occurs in a gasifier, generally a high temperature/pressure vessel where oxygen and steam are directly contacted with the coal or other feed material causing a series of chemical reactions to occur that convert the feed to syngas and ash/slag.
• Syngas can be used for electricity production, used in energy-efficient fuel cell technology, or as chemical “building blocks” for industrial purposes. The hydrogen can also be extracted for use in fuelling a hydrogen economy.
• 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 products.
  • This holds the potential to alleviate the environmental burden by reducing carbon emissions and fostering sustainable practices, contributing to India’s global commitments towards a greener future.
