Biodiesel is defined as the mono alkyl esters of long chain fatty acids
derived from renewable sources. Biodiesel is typically produced through the
reaction of a vegetable oil or animal fat with methanol in the presence of a
catalyst to yield glycerin and biodiesel (chemically called methyl esters).
Biodiesel is registered with the US Environmental Protection Agency as a
pure fuel or as a fuel additive and is a legal fuel for commerce. Biodiesel
is an alternative fuel which can be used in neat form, or blended with
petroleum diesel for use in compression ignition (diesel) engines. Its
physical and chemical properties as it relates to operation of diesel
engines are similar to petroleum based diesel fuel.
Soy enhanced biodiesel is a 100% soybean oil based methyl ester. It
increases the lubricity qualities of diesel fuel, is an effective solvent,
and can be used as in diesel fuel at any inclusion rate (i.e. B2, B20,
etc.). Soy enhanced biodiesel offers significant environmental,
regulatory, and safety benefits as compared to traditional diesel fuel.
- Derived from 100% virgin soybean oil.
- Provides similar performance to conventional diesel
- Highest BTU content of any alternative fuel.
- B20 is designated as an alternative fuel.
- Safest fuel to handle and store: flash point
minimum 212o F.
- Excellent lubricity qualities.
- Biodegradable and non-toxic.
- Ultra low sulfur content.
- Tier 1 and Tier 2 testing completed.
- Decreases EPA targeted emissions.
- The standard storage and handling procedures used
for conventional diesel fuel can be used for biodiesel.
- Fuel should be stored in a clean, dry, dark
- Users of a 20 percent biodiesel blend (B20) will
experience an increase of the cold flow properties (cold filter plugging
point, cloud point, pour point) of approximately 3 to 5o F.
- Precautions employed for conventional diesel fuel
(blending with kerosene, use of cold flow improver, utilization of fuel
tank, fuel filter, or fuel line heaters) are needed for fueling with 20
- Neat or pure (100 percent) biodiesel will gel
faster than conventional diesel fuel in cold weather operations.
- Solutions for winter operability with neat or pure
biodiesel are much the same as that for conventional diesel (blending with
kerosene, use of cold flow improver, utilization of fuel tank, fuel
filter, or fuel line heaters, etc.)
- Users of a 2 percent biodiesel blend (B2) would
need to utilize precautions much like with conventional diesel fuel and
should not experience any measurable differences in cold weather
