Biofuels based on vegetable oils offer the advantage being a sustainable and
environmentally attractive alternative to conventional petroleum based fuel. Biodiesel is
produced from any fat or oil such as soybean oil, through a refinery process called
transesterification. The key issue in using vegetable oil-based fuels is oxidation stability,
stoichiometric point, bio-fuel composition, antioxidants on the degradation and much
oxygen with comparing to diesel gas oil. Biodiesel can be used as a pure fuel or blended
with petroleum in any percentage but the standard storage and handling procedures used
for biodiesel are the main issue due to the biodiesel fuel specifications. In the quest for
fulfill the industry specifications standard; the fuel should be stored in a clean, dry and
dark environment. In this research, three different storage temperature were study which
are; low (0 – 5 °C), ambient (25 – 29 °C), and high (40 – 50 °C). The key parameters
that are required to store biodiesel are discussed, and the recent research advances are
noted. Five types of biodiesel after storage all the samples for 2016 hours were tested
plus with two product of combustion. Images analysis for combustion process was used
to image appearances analysis. Under 2016 hours of storage duration, the effect of
degradation was happen although the effect is not significance because the changes are
still in acceptable ranges
