Summary

Biodiesel is a fuel composed of monoalkyl esters of long-chain fatty acids derived from vegetable oils or animal fats. The conversion of triacylglycerols (TAGs) into biodiesel is a stepwise sequence whereby the alcohol initially reacts as the alkoxide anion with TAG to produce fatty acid alkyl esters (FAAEs) and diacylglycerol. Important properties that are directly influenced by fatty acid (FA) composition include low temperature properties, oxidative stability, kinematic viscosity, exhaust emissions, cetane number (CN), and energy content. Microalgae in particular have attracted considerable interest as feedstocks for biodiesel production, as they have several key traits that make them desirable as energy sources. The many environmental benefits and applications of biodiesel will continue to ensure that a substantial market exists for this attractive alternative to conventional petroleum diesel fuel.
