The present work deals with the volumetric solvent swelling of the cross-linked macromolecular organic matter (kerogen) of Estonian kukersite oil shale in binary solvent mixtures. A two-step solvent swelling procedure was used in which swelling was performed first in one solvent followed by the addition of a second solvent. The results confirm the important role of specific interactions in determining the swelling behavior of this kerogen. The kerogen swells more in strong electron donor solvents that are able to break specific kerogen-kerogen interaction such as hydrogen bonds. When comparing the maximum swelling achieved, the binary solvent mixtures did not perform any better than strong electron donor solvents, regardless of how the experiments were conducted.

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.
