Storage stability of biofuel
Biofuel is one of the prime candidates to take over the role played by fossil fuel as the main source of energy in the future. Numerous studies have been done on the potential of biofuel to produce similar power output generated by the current petrol and diesel which ar...

description |
Biofuel is one of the prime candidates to take over the role played by fossil fuel as the main
source of energy in the future. Numerous studies have been done on the potential of biofuel to
produce similar power output generated by the current petrol and diesel which are depleting
without any drawbacks. The objective of this particular study is to investigate 4 of the more
established vegetable oil in the energy industry namely jatropha, palm, coconut and canola oil in
terms of storage stability of biofuel at room temperature and 80ºC. The biofuels were tested in
terms of density, kinematic viscosity, Total Acid Number (TAN), flash point and oxidation
stability every 2 weeks for 10-12 weeks or 3 months at 2 different temperatures to obtain a
conspicuous result. At the end of the experiment and test, it is found that palm oil is the biofuel
with the best storage stability. The next biofuel that followed is jatropha oil, canola oil and
finally coconut oil. Although palm oil showed poor kinematic viscosity, however it has good
stability in terms of density, Total Acid Number (TAN) and also relatively stable oxidation and
flash point in comparison with the 4 samples tested. The experiment result and data also showed
that effect of continuous heating at 80ºC promotes oxidation process, higher Total Acid Number
(TAN), lower flash point as well as increase in density and kinematic viscosity.
Next, experimental investigations were carried out to evaluate the storage stabilities of various
biodiesel fuels. The biodiesel fuels were palm methyl ester (PME), jatropha methyl ester (JME),
coconut methyl ester (COME), 20% blends of PME with diesel fuel and 20% blends of JME
with diesel fuel. The ordinary diesel fuel was used for comparison purposes. The biodiesel were
tested in terms of density, kinematic viscosity, Total Acid Number (TAN), flash point and
oxidation stability every week for 3 months. The results show that almost all fuel samples met
the standard specifications regarding oxidation stability. The trends for density, viscosity and
TAN increased due to oxidation. For the flash point, the trend also decreased, but the rate was
very low. In overall consideration, among the biodiesel, COME was found to be better with
respect to storage stabilities. The results of this investigation will be used for sustainable
development of biodiesel fuel from various feedstocks. |
