Correlation between refractive indices and other fuel-related physical/chemical properties of pyrolysis liquids derived from coal, oil shale, and tar sand

In the literature, characterization techniques based upon the liquid's refractive index are used with petroleum distillates to predict fuel-related properties: however, essentially nothing has been reported on the application of this technique to pyrolysis liquids. Measurements of the refractive indices of the pyrolysis liquids derived from various feedstocks (coal, oil shale, and tar sand) were made and appear to correlate well with the liquids' physical and chemical properties. The refractive indices of the pyrolysis liquids show good correlations with liquid density (correlation coefficient of 0.98), carbon and proton aromaticities (correlation coefficients of 0.88 and 0.91, respectively), and liquid carbon residue (i.e., correlation coefficient of 0.88 with the Conradson carbon residue). The above and other correlations were developed using data from at least 7 to as many as 35 discrete samples. These correlations have been used to develop empirical models. These findings demonstrate the potential of using the liquid's refractive index as a rapid technique to characterize the fuel-related properties of fossil fuel liquids generated by pyrolysis (before they are hydrogenated).
