Vegetable Oil and BiodieselMelissa Brian
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
Advantages 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
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)
Vegetable Oil:
Advantages 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
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
Biodiesel:
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.
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.
