Biodiesel production through esterification using ionic liquids as catalysts

Bibliographic Details
Summary:There is a growing interest in the development of alternative technologies to the oil economy, based on renewable energy sources. Biodiesel is an alternative fuel that can be produced from a wide range of raw materials such as vegetable oils and animal fats. Yet, the use of sources that do not compete with the food market, such as waste cooking oils - which usually feature high levels of free fatty acids (FFA’s) -, can lead to problems in the process of biodiesel production through alkaline transesterification. Ionic liquids (ILs) could be employed in the biodiesel production to partially overcome these problems; since they are able to catalyze the esterification reaction of FFA’s to biodiesel (FAMEs) as well as the transesterification reaction of triglycerides. Ionic liquids are also viable due to the fact that they can be easily recovered and recycled, decreasing their cost. Experimental results concerning the recyclability of the ionic liquid 1-butyl-3-methylimidazolium hydrogen sulfate [BMIM][HSO4] and its influence on the conversion of organic acids to biodiesel and the content of FAMEs will be presented
