Biomass gasification is considered to be one of the sustainable solutions to the power crisis in India. In this context, which of the following statements is/are correct?
- Coconut shells, groundnut shells and rice husk can be used in biomass gasification.
- The combustible gases generated from biomass gasification consist of hydrogen and carbon dioxide only.
- The combustible gases generated from biomass gasification can be used for direct heat generation but not in internal combustion engines.
Detailed Explanation:
✅ Statement 1 – Correct: Coconut shells, groundnut shells, and rice husk are excellent agricultural residues and biomass feedstock for gasification due to their high carbon content and low moisture.
❌ Statement 2 – Incorrect: The syngas (synthesis gas) from biomass gasification primarily contains carbon monoxide (CO), hydrogen (H₂), methane (CH₄), and carbon dioxide (CO₂), not just hydrogen and carbon dioxide.
❌ Statement 3 – Incorrect: Syngas from biomass gasification can be used for both direct heat generation and in internal combustion engines after proper cleaning and cooling to remove tar and particulates.
