1. Vegetable Oil and Biodiesel
Melissa Brian

3. Vegetable Oil vs. Biodiesel
Biodiesel uses mostly soybeans because it is more efficient than corn
No converting is necessary to run biodiesel, because it acts exactly the same as petrodiesel
To use straight vegetable oil, it first has to be mixed with another fuel then a second tank must be added to the vehicle

5. Vegetable Oil: Advantages Disadvantages
Reduces dependence on foreign countries
Oil can come from anything that is or ever was a plant
Clean burning
Extremely cheap once the conversion tank is added
Can be made at home
We would become dependent on plants, so a famine would be devastating
In vehicles, vegetable oil does not burn in a regular engine (heating tank is necessary)
A lot of pre-heating required (less net energy yield)

7. Advantages Disadvantages
Biodiesel:
Advantages
Disadvantages
Reduces net CO2 emissions by 78% compared to petroleum diesel
Same power and fuel economy as petroleum diesel
47% drop of particulate matter
67% decrease in unburned hydrocarbons
Reduction in Sox gases
Can make it yourself or find a nearby biodieselpump
Freezes and clogs up fuel filters at 28° F
10% increase in Nox gases
If biofuel were grown on every available piece of farmland, it would still only replace 20% of the energy we currently use from crude oil

8. HowSVO(straight vegetable oil) work?
Vegetable Oil can be used for vehicle transportation in 4 ways
Put it in and go… and hope it works.
Mix with diesel fuel (or kerosene), heat to lower viscosity, and put it in and go.
Blend with organic solvent additive or 20% gasoline (petrol), heat to lower viscosity, and put it in and go
Install 2-tank system where the oil is pre-heated.

9. Home Recipe for Biodiesel:
1 liter of new vegetable oil
3.5 grams sodium hydroxide
200 milliliters of methanol
Pour methanol into a glass blender, turn on blender to lowest speed and slow add the sodium hydroxide. Blend until dissolved (2-3 mins) then add in the vegetable oil and blend for mins. Allow the mixture to settle for a few hours. The lower layer is glycerin and the top layer is biodiesel. You can normally use biodiesel in any unmodified diesel engine.
