Which of the following is NOT a source of biomass energy?

  1. Wood

  2. Coal

  3. Manure

  4. Solar Energy


Correct Option: D
Explanation:

Solar energy is not derived from organic materials and is not considered a biomass source.

The process of converting biomass into a gaseous fuel is known as:

  1. Pyrolysis

  2. Gasification

  3. Combustion

  4. Hydrolysis


Correct Option: B
Explanation:

Gasification involves heating biomass in the absence of oxygen to produce a combustible gas.

Which type of biomass is primarily used for biofuel production?

  1. Wood

  2. Agricultural Residues

  3. Forestry Waste

  4. Animal Manure


Correct Option: B
Explanation:

Agricultural residues, such as corn stover and sugarcane bagasse, are commonly used as feedstock for biofuel production.

The process of converting biomass into liquid fuels, such as biodiesel, is known as:

  1. Pyrolysis

  2. Gasification

  3. Transesterification

  4. Hydrolysis


Correct Option: C
Explanation:

Transesterification is a chemical process used to convert triglycerides in biomass into fatty acid methyl esters (biodiesel).

Which technology involves the direct combustion of biomass to generate electricity?

  1. Pyrolysis

  2. Gasification

  3. Combustion

  4. Anaerobic Digestion


Correct Option: C
Explanation:

Combustion is the most common method for converting biomass into electricity, where biomass is burned to produce heat and generate steam.

The process of converting biomass into a solid fuel, such as pellets or briquettes, is known as:

  1. Pyrolysis

  2. Gasification

  3. Densification

  4. Hydrolysis


Correct Option: C
Explanation:

Densification involves compacting biomass materials into a denser form, increasing their energy density and making them easier to handle and transport.

Which of the following is NOT a benefit of using biomass energy?

  1. Reduced greenhouse gas emissions

  2. Renewable and sustainable

  3. Low cost

  4. High energy density


Correct Option: D
Explanation:

Biomass energy has a lower energy density compared to fossil fuels, meaning it requires more volume to produce the same amount of energy.

The process of converting biomass into a gaseous fuel through rapid heating in the absence of oxygen is known as:

  1. Pyrolysis

  2. Gasification

  3. Combustion

  4. Hydrolysis


Correct Option: A
Explanation:

Pyrolysis involves heating biomass rapidly in the absence of oxygen, resulting in the production of a mixture of gases, liquids, and solids.

Which of the following is NOT a challenge associated with biomass energy?

  1. Competition with food production

  2. Air pollution from combustion

  3. High cost of conversion technologies

  4. Abundant and reliable supply


Correct Option: D
Explanation:

Biomass is a renewable and abundant resource, making supply concerns less significant compared to other challenges.

The process of converting biomass into biogas, a mixture of methane and carbon dioxide, is known as:

  1. Pyrolysis

  2. Gasification

  3. Combustion

  4. Anaerobic Digestion


Correct Option: D
Explanation:

Anaerobic digestion involves the breakdown of organic matter by microorganisms in the absence of oxygen, producing biogas as a byproduct.

Which technology involves the conversion of biomass into a liquid fuel through a thermochemical process?

  1. Pyrolysis

  2. Gasification

  3. Transesterification

  4. Hydrolysis


Correct Option: D
Explanation:

Hydrolysis involves the chemical breakdown of biomass using water, resulting in the production of sugars that can be further processed into liquid fuels.

Which of the following is NOT a type of biomass conversion technology?

  1. Pyrolysis

  2. Gasification

  3. Combustion

  4. Photovoltaic Cells


Correct Option: D
Explanation:

Photovoltaic cells are used to convert sunlight into electricity and are not directly related to biomass conversion technologies.

The process of converting biomass into a liquid fuel through a chemical reaction with an alcohol is known as:

  1. Pyrolysis

  2. Gasification

  3. Transesterification

  4. Hydrolysis


Correct Option: C
Explanation:

Transesterification involves reacting biomass with an alcohol, such as methanol or ethanol, to produce a fatty acid methyl ester (biodiesel) and glycerol.

Which of the following is NOT a factor to consider when selecting biomass for energy production?

  1. Availability

  2. Moisture content

  3. Energy density

  4. Toxicity


Correct Option: D
Explanation:

Toxicity is not typically a primary factor considered when selecting biomass for energy production.

The process of converting biomass into a gaseous fuel through a thermochemical process is known as:

  1. Pyrolysis

  2. Gasification

  3. Combustion

  4. Hydrolysis


Correct Option: B
Explanation:

Gasification involves heating biomass in a controlled environment with limited oxygen to produce a combustible gas.
