TL;DR: In this article, a flow type of apparatus is built to give equilibrium gas and liquid samples at elevated pressures and temperatures while minimizing thermal decomposition, and Saturated vapor and liquid compositions and K values are determined with this apparatus for the binary system hydrogen/tetralin (1,2,3,4-tetrahydronaphthalene) at four temperatures from 189.6° to 389.1°C, and seven pressures from 20 to 250 atm.
Abstract: A flow type of apparatus is built to give equilibrium gas and liquid samples at elevated pressures and temperatures while minimizing thermal decomposition. Saturated vapor and liquid compositions and K values are determined with this apparatus for the binary system hydrogen/tetralin (1,2,3,4-tetrahydronaphthalene) at four temperatures from 189.6° to 389.1°C, and seven pressures from 20 to 250 atm. Vapor pressures of tetralin are determined with the same apparatus, and values are reported at the four temperatures of this work.

TL;DR: In this article, the authors identify limiting factors bearing on the chemistry and catalysis in low pressure operation of diesel fuel in the ultralow sulfur regime and show that certain bulk metal sulfides are intrinsically active and selective for desulfurizing 4-substituted and 4,6-disubstitution dibenzothiophenes.

TL;DR: In this paper, the H2 group was added to the well-established PPR78 model in order to predict mutual solubility and critical loci of hydrogen-containing systems, and it was thus possible to estimate the kij for any mixture containing alkanes, aromatics, naphthenes, CO2, N2, H2S and mercaptans regardless of the temperature.
Abstract: The study of phase equilibria in hydrogen-containing mixtures is essential for petroleum and chemical engineering, electricity production, transportation and for many other energy needs. Fluid-phase diagrams are however atypical because of the size-asymmetric nature of these mixtures and the quantum behavior of hydrogen. Therefore, the development of a thermodynamic model able to accurately predict the phase behavior of such systems over wide ranges of pressure and temperature is a difficult and challenging task. In this work, the H2 group is added to the well-established PPR78 model in order to predict mutual solubility and critical loci of hydrogen-containing systems. Such a model combines the widely used Peng–Robinson equation of state (EoS) with a group-contribution method aimed at estimating the temperature-dependent binary interaction parameters [kij(T)]. In our previous papers, 15 groups were defined: CH3, CH2, CH, C, CH4 (methane), C2H6 (ethane), CHaro, Caro, Cfused aromatic rings, CH2,cyclic, CHcyclic ⇔ Ccyclic, CO2, N2, H2S, and SH. It was thus possible to estimate the kij for any mixture containing alkanes, aromatics, naphthenes, CO2, N2, H2S and mercaptans regardless of the temperature. In this study, the addition of the H2 group makes it possible to extend the PPR78 model to hydrogen-containing systems.

TL;DR: For binary mixtures of carbon dioxide with nonane, cumene, propylbenzene, or mesitylene, this article measured the vapor−liquid equilibria for carbon dioxide and propane.
Abstract: Vapor−liquid equilibria were measured for (1) binary mixtures of carbon dioxide with nonane, cumene, propylbenzene, or mesitylene, (2) binary mixtures of propane with nonane, cumene, or mesitylene,...
