Biodiesel is the name applied to renewable fuels manufactured by the esterification of vegetable oils or animal fats which can be used a substitute for or as an additive to mineral diesel. The methyl ester produced using methanol and a basic catalyst is the predominant biodiesel available for compression ignition engines as its properties closely resemble those of No 2 mineral diesel. One of the major technical problems confronting the use of biodiesel fuels is their poor low-temperature properties in comparison with fossil-based diesel fuel. The crystallization temperature of biodiesel fuels is generally higher than that of fossil-based diesel, so the formation of crystals at relatively high temperastures can plug fuel lines and filters causing problems in fuel pumping and engine performance during winter operation. In order to solve the above mentioned problems, several additives such as pour point depressants (PPD), wax dispersant flow improver (WDFI) or wax anti-setting flow improver (WAFI) can be used. In this paper, we reviewed the low temperature properties of diesels (BD5 and BD20) containing several kinds of biodiesels and have tried to find a universal mechanism of PPDs to explain the change of the wax crystals.
