Biodiesel is meant to be used
in standard diesel engines and
is thus distinct from the
vegetable and waste oils used
to fuel converted diesel
Biodiesel is the methyl or ethyl
ester of fatty acid.
The 1’st use of peanut oil was
made in 1895 by Dr. Rudolf
Following trees are used for
4. Manufacturing process
triglycerides diglycerides monoglycerides
Yielding one methyl ester molecule from
glyceride at each step.
When methonol is used in the esterification,a
catalyst & excess alcohal are used to increased
rate of reaction & to the shift the equilibrium to
the product side respectively.
Used in compression ignition engine.
No modification of diesel engine for
Biodiesel fuel is same to diesel fuel but is
Biodiesel is safe and non-polluting source
7. Availabilities and prices
Global biodiesel production reached 3.8 million tons in 2005.
Approximately 85% of biodiesel production came from the
Biodiesel is now being produced locally in India for use in
stationary engines and large or slow engines like those in trains,
trucks and tractors.
Efforts are also on to use ethanol as a substitute for petrol.
Biodiesel is rapidly replacing both kerosene (which was used
illegally and inefficiently) and diesel as a more efficient, cheap,
and clean alternative for large engines.

Biodiesel is safe to handle because it is
biodegradable and non-toxic.
Biodiesel reduces all the emission.
Biodiesel can be used alone or mixed in
any amount with petroleum diesel fuel.
Biodiesel runs in any conventional,
unmodified diesel engine.
10. Future scope of biodiesel
Biodiesel is a safe alternative fuel to replace
traditional petroleum diesel.
It has high-lubricity, is a clean-burning fuel and
can be a fuel component for use in existing,
unmodified diesel engines.
Biodiesel acts like petroleum diesel, but produces
less air pollution, comes from renewable sources,
is biodegradable and is safer for the environment.
In the United States today, biodiesel is typically
produced from soybean or rapeseed oil or can be
reprocessed from waste cooking oils
