Prediction of Surface Tension of Heteroatom-Rich Fuel Fractions from Pyrolysis of Oil Shale

Abstract

In this work, a brief overview of the methods for calculating surface tension and analyze various methods for calculating Parachor and surface tension for Kukersiite shale oil fractions. Using experimentally measured data on the surface tensions, densities and average boiling points of the industrial gasoline and middle oil fractions of oil shale, a proposed correlations for calculating both the surface tension at 20°C and for calculating the temperature dependence of the surface tension (in the temperature range from 10 to 180°C). These correlations enable the calculation of surface tension at 20°C and the temperature dependence of the surface tension with a relative accuracy of ±5.5%. The resultingcorrelation also makes it possible to find temperature dependencies of the surface tension of alkanes and oil fractions, for example, with an error generally below 10%
