Abstract: New correlations are developed to calculate the molecular weight, the carbon to hydrogen weight ratio, and the aniline point temperature for petroleum fractions and coal liquids over a wide range (70 < MW < 1,685 g/mol, 5.4 < C/H < 15.1, and 45.5 < AP < 106.4 °C), using the average boiling point and the standard specific gravity as input parameters. The developed correlations are more accurate than similar ones in the literature with squared correlation coefficients of 0.9853, 0.95 and 0.9452 for MW, C/H and AP, respectively. The proposed correlations have the advantage of combined accuracy, simplicity and convenience compared to similar methods. They cover a wider property range and apply to petroleum fuels and coal liquids as well. In addition, examples are provided to utilise the predictions of the developed correlations to calculate the average molecular formula for fuels and coal liquids.
