Biodiesel From Plant Oils And Algae Flashcards
What is the problem to witching to biodiesel from plant oil?
Most cars aren’t equipped to handle it and it can damage modern engines
- due to incomplete combustion
What prices does the oil undergo to convert to biodiesel?
Transesterification
What is good about soybean biodiesel?
Generates 90% more energy than is used to produce it
What is formed during the tranesterification?
Glycerin or triglycerides
What is used to turn triglycerides from the oil into biodiesel?
Methane
- crested from fossil fuels so this process isn’t 100% renewable
Ideal conditions for growing algae?
Large ponds with lots of sun so they can produce lots of oil
What conditions does algae need in order to produce the most oil?
They have to be nutrient deprived
Problems with oil
- has more than 4 CC double bonds
- more susceptible to oxidation during storage
How to prevent oxidation of the oil?
Partial hydrogenation
- when H2 gas is added to the double bond to make it less reactive
Why is parties hydrogenation kinds of bad?
Because H2 is only derived from the extraction of natural gas
- therefore not 100% renewable
Why are leant oils viscous?
Their components are large molecules
- preheat to become more fluid
