Jatropha Curcas is a special and unique
plant. It is often called physic nut, wonder plant or gold plant because of its
high economic advantage. Curcas is a diesel bearing plant. It can withstand
high degrees of aridity and so can be grown even in desert areas. Jatropha
shrubs begin to fruit from the first year and come to full maturity within five
years, with a lifespan of up to 45 years, delivering an estimated over 1,500
gallons of diesel per acre per annum.
It is a non-edible plant that can be
cultivated in arid, semi-arid and fertile ground. The seeds when dried and processed
contain about 40 per cent oil which could serve as bio-diesel that can be used
in standard diesel engines or further processed into aviation fuel, bio-kerosene,
bio-petrol and glycerol which is used as a sweetener by confectioners. The cake
can be used in fertiliser production as it is a rich source of NPK, production
of animal feeds, poultry feeds, insecticide, production of cooking gas and
electricity generation while the oil can be used for production of antifungal
soaps, shampoos, creams, candles, Turkey red oil and adulteration of olive oil.
Part of the by-product of Jatropha Curcas is glycerin which is used as a moisturizer
in cosmetics manufacturing. Glycerin is also applied in the textile industry as
a plasticizer.
METHOD OF EXTRACTING
JATROPHA OIL FROM THE SEED
Oil Presses Method
Oil
presses method is used to extract the oil using simple mechanical devices. It
is also done manually. The most commonly used oil presses method is the
Bielenberg ram press method. Bielenberg ram press method is a simple
traditional method that uses simple devices to extract the oils. With the help
of this method 3 liters of oil can be obtained with 12 kg of seeds.
Oil Expellers Method
Oil
expellers method is also use for jatropha oil extraction. The most commonly
used method is the Sayari oil expeller method. This method is also called as
Sundhara oil expeller. Komet oil expellers are also used. These sayari oil
expellers was developed in Nepal and is a diesel operated one. Now it is developed
in Tanzania and Zimbabwe mainly for the production jatropha oil. Heavy oil
expellers are made of heavy cast iron and the light ones are made up of iron
sheets. Electricity driven models are also available. Komet oil expeller is a
single oil expeller machine that is used not only to extract the jatropha oil
as well for the preparation of the oil cakes.
Traditional Methods
Traditional
methods are used in the rural and developing areas for extracting the oils.
Traditional methods are simple and the oil is extracted by hand using simple
equipment.
Hot oil extraction Method
The
process of extracting the oil at high pressure is called as hot oil extraction
method. Since jatropha oil can regulate the operating temperature it is
extracted using the hot oil extraction method. Then the cold oil extraction
method it is easy to extract the oil from the hot oil extraction since the oil
flows more easily due to higher viscosity. And the press cake that remains
after extracting the oil also have less oil content which might be 3 to 7 %
approximately. These two reasons make the oil press method very interesting. During
the oil extraction method many stuffing of the seeds are converted into gum
like substances and some non organic substances. These are unwanted products
and so they have to be refined.
Modern Concepts Method
Modern
methods are followed to extract more oils from the jatropha seeds. In these
modern concepts chemical methods like aqueous enzymatic treatment is used. The
maximum yield by following this modern method is said to be about 74/5. The
main idea in researching the modern concepts is to extract a greater percentage
of oil from the jatropha seeds.
BIODIESEL MANUFACTURING
PROCESS
The
raw material required for Jatropha Biodiesel manufacturing are: Jatropha oil, Methanol,
Potassium hydroxide, Isopropyl alcohol, Distilled water, Phenolphthalein
solution, Vinegar and Water. First jatropha oil is filtered to remove the solid
particles present in it. Then it is heated to remove the water contents if any
present in it.
Biodiesel
is now been used as a diesel engine in number of agencies. The results are said
to be comparable with petroleum in all the areas like power, efficiency,
climbing, hauling etc. To determine the amount of catalyst that is required for
catalyst. The accurate amount of potassium hydroxide is mixed with methanol
till the methanol completely dissolves to get potassium methoxide.
In
the winter season additional jatropha oil is heated and is mixed with the
potassium methoxide. The mixture is allowed to settle. In this process glycerin
settles at the bottom and the biodiesel at the top. The glycerin is then
removed and the biodiesel is washed and dried.The biodiesel that is obtained is
then checked for quality
Note:
In this process when methanol and potassium hydroxide to produce potassium methoxide which when mixed with oil produces strong polar bond. This breaks the fatty acids into glycerin and biodiesel (esters). These esters later become methyl esters. When the KOH is treated with ethanol it will form ethyl esters.
Export Market
The export market for Jatropha Curcas
is high. It can be exported in various value added form like Jatropha Seed,
Jatropha Oil, Jatropha Biodiesel. The export market is available in India,
Pakistan, Japan, Cote de Voir, Ireland, Malaysia e.t.c. Jatropha can be sourced
from most part of Nigeria but the Northern part of Nigeria has a big share in
the Jatropha plant cultivation. If
