General description
of practical
biodiesel fuel |
 |
General description
Present biodiesel is liquid fuel, which is obtained
by methyl esterification of fatty acid.
The main constituent is fatty acid methyl ester. |
 |
Main usage
Mixture usage with diesel and heavy oil or alternative
usage for engines.
Mixture usage with kerosene and heavy oil or
alternative usage for engines. |

Biodiesel Fuel is an alternative
fuel for diesel, which is composed of recyclable materials
like fatty acid of plant and animal origin.
Using biodiesel will enable us to clear exhaust gas standards
for diesel engine.
The production process of present practical biodiesel
fuel is methyl esterification of trigliceride by
alkorisis, and its product is called first generation
of biodiesel.
FAME of rape seed oil or sun flower oil is used
in environmentally developed countries in EU, while
FAME of soybean oil has been put in use since 1990s
in US. FAME of cooking oil waste has been used in
several areas in Japan as a biodiesel fuel. |

| Majoy plants used
in biodiesel production |
Almost all animal and plan fatty acids
can produce biodiesel fuel,
however the following raw materials
are mainly focused. |
 |
|
|
|
| Yield
of palm is big but its price is unattainable
in terms of the strong interest from the
world. |
|
Jatropha
is durable at terrible atmosphere.
It can survive in desert so it can be used
as greening effect.
Good quality oil can be squeezed.
its cost is cheap and its production is stainable
for fuel in terms of impossible transferring
to food.
Jatropha can be used for two methods, biodiesel
fuel and greening effect, so its reputation
is quite high. |
|
Waste
cooking oils are used for recycle purpose
instead of the measure for greenhouse effects.
The quality control is difficult to do because
their mixed oils.
It is also difficult to scale up the supply
in terms of their volume. |

|
| Sun
flower, soy bean, and rape seed are mainly used
as raw materials in Europe and the United States.
Their usages are depend on their harvest area. |

Can vegetable oil be used directly as an alternative
fuel for engines?
Vegetable oils have high flash point, so they cannot
be combusted in engines.
That is why vegetable oils require transformation
with methyl ester for alternative fuels by reducing
flash points. |
