Subtopic: Bio-fuels and their use in farm mechanization
Question Statement:
Match the processes given in Group-I with the derived products given in Group-II:
| Group-I (Processes) | Group-II (Derived Products) |
|---|---|
| i. Transesterification | a. Producer gas |
| ii. Pyrolysis | b. Ethanol |
| iii. Yeast fermentation | c. Biogas |
| iv. Anaerobic digestion | d. Biodiesel |
Options:
(A) i-a; ii-c; iii-b; iv-d
(B) i-d; ii-c; iii-b; iv-a
(C) i-b; ii-d; iii-a; iv-c
(D) i-d; ii-a; iii-b; iv-c
Official Answer Key:
D
Step-by-Step Solution & Explanation
Transesterification of vegetable oil/fat with an alcohol yields biodiesel (i→d). Pyrolysis (thermal decomposition in absence of O₂) of biomass yields producer gas (along with char/tar) (ii→a). Yeast fermentation of sugars yields ethanol (iii→b). Anaerobic digestion of organic matter by bacteria yields biogas (iv→c). Answer: (D).
