Résumé

Lignocellulosic biomass refers to plant biomass that is composed of lignin and cellulose (wood residues, cereal straw and forestry waste). This biomass is playing a major role in the chemical sectors as a substitution material. The thermodynamic behaviour of molecules associated with the conversion of these bio-resources is poorly understood but is of importance for the design and the development of new processes. In this paper, we focus on the furan as a derived molecule. To the best of our knowledge, no data are available in the open literature; as a result, a study of some thermodynamic properties has been initiated for the binary systems of furan with n-hexane, toluene or 1-Octanol. The volumic mass of pure compounds and of binary liquid mixtures has been measured from 303.15 K up to 383.15 K for pressures up to 2 MPa with an Anton Paar vibrating-tube densimeter DMA HPM. Excess molar volumes were calculated from experimental data and fitted using the Redlich-Kister polynomial equation. The excess molar enthalpies for binary mixtures cited above were obtained at three temperatures ranging from 313.15 to 383.15 K. The measurements were performed using a customized flow mixing unit adapted to the BT215 calorimeter, manufactured by SETARAM Instrumentation France. The experimental results are represented and correlated using a Redlich-Kister type equation. Modelling of the excess enthalpies has been performed using the UNIFAC molecular group-contribution method.
