“…Prior to measurements of both the compressed-liquid density and the ambient-pressure density and dynamic viscosity, the sample was degassed following our standard procedure. , First, sample was transferred to a secondary container (stainless steel cylinder and glass bulb for compressed-liquid and ambient-pressure measurements, respectively). The sample was then frozen by submerging the container in liquid nitrogen.…”

Densities of a 50/50 by volume mixture of JP-10 + a turpentine dimer fuel (TDF) have been measured in the compressed-liquid state from 270 to 470 K and at 0.5−45 MPa and at ambient pressure from 263.15 to 373.15 K. Ambientpressure dynamic viscosity has also been measured over the same temperature range. The density data have been correlated with a Rackett equation, and the compressed-liquid density data have been fit to a Tait equation. Correlation parameters are given. Results of the mixture measurements presented here are compared with previously measured densities of the individual components, TDF and JP-10. Measurements of density over large ranges of temperature and pressure, as well as viscosity measurements, provide information as to the suitability of a fuel for use as a drop-in replacement for traditional petroleum-based fuels. The large range in temperature and pressure of the measurements is important to more closely capture engine operating conditions and better access the potential of alternative fuel candidates.

“…This comparison is given in Figure 5 and Figure 6, and shows that the shale oil samples have relatively low compressibilities. The petroleum fraction was a narrow distillation cut with an average boiling point of about 523 K. 45 The bio-derived jet fuels consisted mostly of linear and branched paraffins (BIO-SPK and Cs-HRJ samples in 46 ). The curves shown in the figures were calculated by fitting polynomials to the experimental data given in the references and then using those polynomials to calculate the compressibility.…”

The temperature and pressure dependence of density was measured experimentally from 293 to 473 K and 0.1 to 12 MPa for a shale oil produced from Kukersite oil shale in Estonia. The shale oil sample was a fuel oil fraction of a whole oil produced in a commercial plant that uses solid heat carrier retorting technology. The fraction had a boiling range of approximately 460 to 780 K and contained significant quantities of polar phenolic compounds (hydroxyl group content of 5.3 wt%). The effect of these compounds on the properties of the oil was investigated by removing most of the phenolic compounds via extraction to create the second sample (dephenolated sample with hydroxyl group content of 1.1 wt%). The dephenolation resulted in a shale oil with a composition being more similar to that of other shale oils from well explored deposits. Based on a review of the literature, this is the first experimental data on the pressure dependence of density for this shale oil, and shale oils generally. Thermal expansion coefficients, isothermal compressibilities and speeds of sound were calculated from the experimental data. Empirical relationships describing the temperature dependence of the heat capacities between 288 and 423 K at atmospheric pressure are also presented here.

The pressure-volume (density)-temperature (P-r-T) surface of a fluid presents the basic thermodynamic properties for investigating the behaviour of fluids. The isothermal compressibility, k T , and isentropic (adiabatic) compressibility, k S , of a fluid are defined as:(13:1)where r refers to the specific molar volume, P to pressure, T to temperature and S to entropy. The pioneering studies on the P-r-T relationships for various compounds were conducted by Bridgman, 1,2 Gibson and Kincaid 3,4 and many colleagues in the early 20th century. Today, the experimental P-r-T data of a large number of liquids and/or mixtures have been stored or published in a variety of styles. Examples include the databases of Volume Properties: Liquids, Solutions and Vapours Edited by Emmerich Wilhelm and Trevor M. Letcher
