FAME (Fatty Acid Methyl Esters) Biodiesel Explained \u2013 An Easy Guide<\/h2>\n\n\n\n

FAME (Fatty Acid Methyl Esters) are acids that are created during the transesterification of vegetable oils and animal fats that create biodiesel.<\/p>\n<\/div>\n\n\n\n

    How is FAME diesel created?<\/h2>\n\n\n\n

    FAME (Fatty Acid Methyl Ester) is the generic chemical term for biodiesel derived from renewable sources. It is used to extend or replace mineral diesel and gas oil used to fuel on and off-road vehicles and static engines.<\/p>\n\n\n\n

    Current pump diesel can contain up to 7% FAME, however, higher levels of FAME content, even up to 100% FAME (B100), are not uncommon.<\/p>\n\n\n\n

    It’s created during the transesterification of vegetable oils and animal fats to make biodiesel. These high molecular weight oils and fats react with short chain alcohol in the presence of a catalyst, usually potassium hydroxide, to produce lower molecular weight esters (FAME).<\/p>\n\n\n\n

    What is transesterification?<\/h2>\n\n\n\n

    Transesterification involves splitting the three alkoxy groups from the glyceryl backbone of the triglyceride (oil\/fat). Reaction with the alcohol produces three lower molecular weight esters (FAME) and liberates glycerol as a by-product. Potassium hydroxide acts as the catalyst in the reaction.<\/p>\n<\/div>\n\n\n\n

    What can FAME biodiesel be produced from?<\/h2>\n\n\n\n

    A wide variety of oils and animal fats can be used to produce FAME fuel. The most commonly used oils and fats include:<\/p>\n\n\n\n
