The methyl esters of the higher fatty acids C14-C22, biodiesel, which can be derived from vegetable oils and animal fats via transesterification with alcohol, may be usable as an alternative fuel for diesel engines. This compound is also referred to as a biodiesel fuel. However, it also holds tremendous promise in a wide range of industrial purpose, either in direct form or as starting materials for the production of other compounds. The behavior of fuels under low temperature is an important quality criterion in the winter. Cold-filter plugging point (CFPP) of biodiesel is a main parameter in quality test and enhancement of biodiesel quality. In this study, we have attempted to determine an equation or technique for estimation of CFPP in biodiesel by using the different compositions of biodiesel derived from several sources.
