Biodiesel manufacture is one of the advanced
and technical areas for researchers as it is conquering
the world because of petroleum shortage and increasing
rate together with the environment friendly nature.
Biodiesel define as the mono-alkyl esters of fatty acids
prepared through trans-esterification reaction.
The use of biodiesel is increasing rapidly worldwide
due to its positive impact on diesel engines, combustion
processes, and pollution formation. Biodiesel is a wellknown derivative of long-chain fatty acids that can be
obtained from renewable sources such as vegetable oils
or animal fats. It can be effectively used in diesel engines.
The process of preparing biodiesel from raw materials,
such as cottonseed oil, involves the trans-esterification of
fat, followed by biodiesel characterization testing.
Cottonseed oil, non-edible oil, was chosen as the raw
material for this experiment, as it does not contribute to
food versus fuel conflict. Methanol was used as a catalyst
in the trans-esterification process for biodiesel
preparation. However, the optimum conditions for
biodiesel production are suggested in this paper, a
maximum of 77% biodiesel was produced with 20%
methanol in presence of 0.5% sodium hydroxide.
Furthermore, after the preparation of biodiesel, for its
identification, numbers of test was done and the
prepared biodiesel was verified.
