Enthalpy and phase behavior of coal derived liquid mixtures. Technical progress report, October-December 1985
On July 15, 1984, work was initiated on a program to study the enthalpy and phase behavior of coal derived liquid model compound mixtures. During the sixth quarter, preliminary enthalpy measurements for the 1/3:2/3, 1/2:1/2, 2/3:1/3 m-cresol tetralin binary mixtures have been completed and are included in a section at the end of this report. Vapor liquid equilibria measurements for the m-cresol/tetralin system are in progress for four isotherms. Tetralin vapor pressures are reported in this report from both the VLE apparatus and the calorimeter. In addition, ongoing research into the modeling of polar systems has led to an approach for modifying the Soave equation of state. This equation of state introduces a polar parameter which appears to be related to the expected strength of polar interactions for different compounds. The appendix contains the paper on this work titled ''Approach for extending Van de Waals equations of state for polar, hydrogen bonding fluids applied to the Soave equation of state''. This article has been processed separately for inclusion in the Energy Data Base.
