This report documents the results of the first phase of the evaluation of a selected set of models used to represent the dependence of important thermophysical properties on the state variables in VLE and heat and material balance calculations. The models considered were the conformal Solution Theory BWR equation of state, the ASPEN modification of the Redlich-Kwong-Soave equation of state, and a combination of the Grayson-Streed correlation (for VLE) with the Lee-Kesler equation of state (for enthalpies). An approach proposed in Task 1 for determining the parameters of these models from the commonly measured properties (normal boiling point and specific gravity) was also evaluated. In the first phase only the properties of pure components and narrow-boiling coal liquid fractions treated as pure components (or pseudocomponents) were considered. The data used in the evaluation consisted of a subset of the model compound data compiled in Task 1, and vapor pressure data for the coal liquid fractions from the Liquefaction Technology Data Base maintained by PETC. The BWR equation was the best model among those evaluated, and the proposed parameter determination approach was found to be an effective means of obtaining consistent parameter values from the measurable data.
