Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Non-edible vegetable oils are chemically converted into renewable liquid transport fuels via catalytic transesterification.
Step 2: Detailed Explanation:
Jatropha (Jatropha curcas) seed oil contains high levels of triglycerides.
During transesterification, triglycerides react with an alcohol (methanol or ethanol) in the presence of an alkaline catalyst (such as $\text{KOH}$ or $\text{NaOH}$) to yield fatty acid methyl esters (FAME, known commercially as bio-diesel) and glycerol as a byproduct.
Step 3: Final Answer:
Therefore, transesterification of Jatropha oil produces bio-diesel.
