Interpretive Summary:

Technical Abstract: Biodiesel, the alkyl esters, usually methyl esters, of vegetable oils, animal fats, or other triacylglycerol-containing materials, are the most common approach to producing a fuel from the mentioned materials. This fuel is obtained by transesterifying the oil or fat with an alcohol, usually methanol, in the presence of a catalyst such as alkoxide or hydroxide. In more recent years, a fuel, probably best termed renewable diesel, has been developed which simulates the composition of conventional diesel fuel. This fuel is obtained by hydrotreatment of the triacylglycerol-containing materials. Even more recently, a decarboxylation process of fatty acids was reported which provides a mixture of long-chain alkene isomers and other products with potential fuel properties. The three materials are compared regarding their production, composition, and properties.
