Vapour-liquid equilibrium for beta-myrcene and carbon dioxide and/or hydrogen and the volume expansion of beta-myrcene or limonene in CO2 at 323.15 K

Research output: Contribution to journalArticlepeer-review


Vapour-liquid equilibrium measurements for binary and ternary (carbon dioxide + beta-myrcene and carbon dioxide + beta-myrcene + hydrogen) systems have been carried out at 323.15 K and pressures in the range from 7 MPa to the critical pressure of the binary mixture and at pressures from 10 to 14 MPa for the investigated ternary systems. Samples from the coexisting phases were taken, and compositions were determined experimentally. Results were correlated using the Peng-Robinson and the Soave-Redlich-Kwong equations of state with the Mathias-Klotz-Prausnitz mixing rule. The set of interaction parameters for the employed equations of state and applied mixing rule for the system of CO2 + beta-myrcene and of CO2 + beta-myrcene + H-2 were obtained. Additionally, the volume expansion of the liquid phase for the binary mixtures (carbon dioxide + beta-myrcene and carbon dioxide + limonene) were measured at 323.15 K and at pressures from 4 MPa up to very close to the critical pressure of the mixture. The ratio of liquid phase total volumes at the given pressure and at 4 MPa was calculated. (C) 2009 Elsevier B.V. All rights reserved.
