Oil seeds represent a sizable fraction of the feedstocks that are used to generate biodiesel fuel today. In this lab investigation, students will use oil derived from seed plants (canola and soy) to synthesize biodiesel fuel. Students may also utilize used cooking oil (canola and soy) for biodiesel conversion. Students will then analyze each fuel for yield, purity (freezing point test), combustibility, and particulate formation (during combustion).
Learning Objectives
Upon completion, students will be able to:
- Conduct and understand a transesterification reaction.
- Evaluate and determine the ‘best’ feedstock to use for biodiesel fuel using qualitative parameters of purity, yield, and combustion particulate analysis.
