• A. i only
• B. ii, iii
• C. All
• D. ii only

Answer 1

Answer:

A. i only

Biomass gasification 

• Biomass gasification is a thermochemical process that converts biomass materials into a gas mixture primarily consisting of carbon monoxide (CO), hydrogen (H2), methane (CH4), and carbon dioxide (CO2).
• The exact composition of the gases can vary depending on the feedstock and gasification process.
• This process is an important renewable energy technology with several applications, including electricity generation, heat production, and the production of biofuels and chemicals.
• Coconut shells, groundnut shells,rice husk and various other agricultural and forestry residues can be used in biomass gasification.
• The combustible gases produced through biomass gasification, often referred to as syngas or producer gas, can indeed be used for various applications.
• They can be used for direct heat generation, such as in boilers and furnaces, but they can also be used as a fuel source for internal combustion engines to generate electricity or power vehicles.
