Modeling the properties of pyrolysis oil

Based on new experimental data for Kukersite shale oil, it is now possible to develop a property prediction model for the gasoline fraction of shale oil. Such a model was created based on estimation of the composition along with experimental boiling point and density data. First, correlations were developed to estimate the composition of a Kukersite shale gasoline sample based on the boiling point and density of narrow fractions. The estimated composition was then used with the PC-SAFT equation of state to calculate the properties of shale gasoline. To do so, correlations were developed to predict the PC-SAFT parameters of the various classes of compounds present in Kukersite shale gasoline. The utility of this model was shown by predicting the vapor pressure of various portions of the shale gasoline.
