Coal Gasification:
The Ministry of Coal has signed the Coal Gasification Plant Development and Production Agreement (CGPDPA) with selected applicants under Category II of the Coal Gasification Financial Incentive Scheme.
- Coal gasification 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.
