Abstract

Biodiesel is a renewable fuel that is commonly used in diesel engines around the world mostly in blends with the conventional diesel. There are many studies concerning its production and its properties and a series of them confirms the biodiesel advantages when compared with conventional diesel in relation of the environmental impacts. In spite of many advances concerning the biodiesel production and properties its behavior at low temperatures is worst than the conventional diesel, and, unfortunately, low temperature property information concerning fatty acid ethyl esters (FAEE) and the biodiesel is still scarce for researchers. This paper presents nine solid-liquid phase diagrams of FAEE binary mixtures to complement the studies of FAEE phase diagram previously reported. All of the phase diagrams have been determined using differential scanning calorimetry (DSC) and also modelled using both the Predictive UNIQUAC and the ideal solution models. The results have been shown good correlation between experimental and modelled data. (C) 2016 Elsevier B.V. All rights reserved. (AU)
