Alves, Alanderson Arthu Araujo; de Medeiros, Lucas Henrique Gomes; Feitosa, Filipe Xavier; de Sant’Ana, Hosiberto Batista published the artcile< Thermodynamic Properties of Biodiesel and Petrodiesel Blends at High Pressure and High Temperature and a New Model for Density Prediction>, Formula: C19H34O2, the main research area is thermodn property biodiesel petrodiesel blend density modeling.
This paper presents a new model to predict the d. of biodiesel + petrodiesel mixtures at high pressure and high temperature (HPHT) based on the Murnaghan equation of state, as a function of temperature, pressure, volumetric composition, and petrodiesel and biodiesel densities. This model was validated by using exptl. data from the literature, along with a new exptl. data set for biodiesel (grape seed, corn, and linseed) + petrodiesel, at high pressure (0.10-100.00 MPa) and high temperature (293.15-413.15 K) in a composition range of 0, 20, 40, 60, 80, and 100%volume These exptl. data were correlated by using the Tammann-Tait equation. From these data, the following derivative properties were determined: isothermal compressibility (κT), isobaric thermal expansibility (αP), internal pressure (pint), and the difference between pressure and volume heat capacities (cp – cv). Deviations obtained from the model proposed in this work (%AARD) were less than 0.50% for biodiesel + petrodiesel d. data.
