Résumé:
Disposing of cooking oil incorrectly causes serious environmental problems,
such as the pollution of fauna and flora. This oil that often ends up being
spilled into sink drains in several homes cause environmental problems
serious, can be recycled and used to produce biodiesel, thus eliminating more
a polluting residue. Biodiesel is a clean burning fuel produced from
from renewable sources such as animal fat and oil seeds. The production of
biofuels have a great social appeal, as the release of gases that cause the
The greenhouse effect has increased over the decades, and one of the great
cause of the release of these gases are the cars and engines that use as
fuels oil derivatives, so measures have been taken to ensure that
can create a substitute that is less polluting than fossil fuels, and also
that it is renewable since it is estimated that oil reserves will run out someday. O
transesterification process is a reversible reaction that will transform a molecule
of triglyceride (soy/kitchen oil) into ester molecules using as an agent
transesterifier a short-chain alcohol (methanol or ethanol). The present work had
as the objective to recycle and use the residual soy oil from the university restaurant of the
Federal University of Campina Grande Cuité campus for biodiesel production,
as well as evaluating the physicochemical parameters of the raw material and the two esters
that were obtained (methyl and ethyl). Esters were produced with yield
satisfactory and presented physicochemical parameters suitable for its use as
biofuels.
