  1. Vegetable Oil and Biodiesel Melissa Brian

  2. 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

  3. Vegetable Oil: Advantages Disadvantages 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) • 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

  4. Biodiesel: Advantages Disadvantages 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 • 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

  5. 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.

  6. 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 20-30 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.
