Biodiesel Quality, Standards and Properties

摘要: Quality is a prerequisite for the long-term success (successful use, without technical problems) of biofuel. Biodiesel quality depends on several factors that reflect its chemical and physical characteristics. The biodiesel can be influenced by number factors: feedstock; fatty acid composition parent vegetable oil or animal fat; production process other materials used in this process; postproduction parameters; handling storage. Given fact most current diesel engines are designed to powered fuel, physicochemical properties should similar those oil. This chapter presents main standards commercial adopted different regions world importance significance regulated (cetane number, density, viscosity, low-temperature performances, flash point, water content, etc.) unregulated (elemetal composition, methyl ethyl esters heating value, lubricity, etc.). Properties obtained from feedstocks1 presented based mainly data published specialized literature, but also personal research.
