Biodiesel is a well-known biofuel that consists in a mixture of fatty acid methyl esters (FAMEs) of diesel quality that can be produced from vegetable oils, animal fats or cooking waste oil through the transesterification of the triglycerides with methanol, a reaction also named methanolysis.Biodiesel has the potential of making a valuable contribution to a more sustainable energy system, particularly for the transportation sector.For this reason, there is great interest in the intensification of biodiesel production in order to improve the production process efficiency and reduce its costs and environmental impact [1].
