  Background:
Biodiesel and renewable diesel are alternative diesel fuels,
derived from biological sources (such as vegetable oils or tallow),
which can be used in unmodified diesel-engine vehicles.
To
produce biodiesel, a feedstock (commonly vegetable oil) undergoes an esterification reaction
with methanol and a catalyst to produce Fatty Acid Methyl Esters
(FAME). Renewable diesel is produced by hydrotreatment of the
same
feedstocks as biodiesel, resulting in a hydrocarbon fuel that is very
similar to
petroleum diesel in its chemical composition.
Most
commonly these fuels are used in a blend with petroleum diesel.
For example, B5 would be a mixture containing 5% biodiesel
and
95% petroleum diesel, whereas R20 would be a mixture containing 20%
renewable diesel and 80% petroleum diesel. |
