Abstract

Recently, an increasing effort has been devoted to the search of new self-sustainable liquid biofuels that allow overcome some limitations of ethanol, such as, low energy density, high volatility and contamination by the absorption of water from the atmosphere. 2,5-dimethylfuran (DMF) is a heterocyclic compound that can be used as liquid fuel and shows superior characteristics when compared to ethanol. The DMF production process starts with the acid-catalysed dehydration of fructose (a carbohydrate obtained directly from biomass) to produce 5-hydroxymethylfurfural (HMF) in a biphasic reactor, followed by separation, conversion and purification steps. The separation and purification steps require a deep knowledge of the liquid-vapor phase equilibrium behavior. Determination of vapor-liquid equilibrium data (VLE) and thermodynamic modeling allow characterize and describe the phase behavior of a system and they are also needed to design, model and simulate a DMF production plant in order to energy saving and reduce equipment costs. The objective of this project is determining experimentally the liquidvapor equilibrium data for binary systems containing: HMF + water/HCl; DMF + 2-methylfuran and DMF + water and the ternary system composed of 2-methylfuran + DMF + water at 90, 100, 120 ºC. The VLE data will be submitted to thermodynamic consistency test and correlated using activity coefficients models for the liquid phase: Wilson, UNIQUAC and/or NRTL equations, while, for the vapor phase, the fugacity coefficient will be calculated using the VIRIAL equation.
