Correct option is B
Pyrolysis is a thermochemical decomposition process carried out at high temperatures in the absence of oxygen, primarily used to convert biomass into bio-oil, syngas, and biochar. It is not a biochemical process and does not produce ethanol, which is typically obtained through fermentation. Pyrolysis generates minimal waste, and its bio-oil acts as a viable substitute for heating oil, offering an alternative to conventional fossil fuels. Hence , B, C, D only is the corrrect option .
Information Booster:
- Pyrolysis temperature range: 300°C–600°C.
- Types of pyrolysis: Fast pyrolysis, slow pyrolysis, and flash pyrolysis.
- Bio-oil from pyrolysis can be upgraded for transport fuels.
- Biochar, a byproduct, enhances soil fertility and carbon sequestration.
- Pyrolysis aids in waste-to-energy conversion, supporting circular economy models.
Additional Knowledge:
A - Biochemical Conversion Process:
- Refers to anaerobic digestion or fermentation.
- Examples: Ethanol from sugarcane, biogas from organic waste.
- Not applicable to pyrolysis, which is thermochemical.
E - Production of Ethanol:
- Ethanol is derived through fermentation of carbohydrates.
- Primary feedstocks: Sugarcane, maize, molasses.
- Ethanol production is unrelated to pyrolysis.
