A generalied corresponding states principle based on two nonspherical reference f l u b has been used to correlate and predict the viscosities and thermel conductiviis of mixtures of interest in synfuels process design. It is shown that an appropriate choice of reference fluids leads to good Predictions of the transport properties over a range of pressures and temperatures for both defined and undefined mixtures. The need for reference fluid transport property data is discussed.

A generalized corresponding states principle (GCSP) based on the known properties of two reference fluids has been used to correlate the viscosities of fluid mixtures over a wide range of pressure and temperature. It is shown that good predictions of the viscosities for a variety of mixtures can be obtained with this method. Asymmetric mixtures, however, require the use of one adjustable constant. Comparisons with the TRAPP method are shown and the advantages and limitations of the two methods are discussed.
