摘要

The calculated thermodynamic functions of a primary coal tar fraction with a final boiling point of 300 degrees C were presented for the modeling of hydrogenation products using an additive method. Based on model reactions of the hydrogenation of o-cresol, it was demonstrated that the hydrogenation of an aromatic ring is more likely than the hydrogenolysis of the bonds of methyl and hydroxyl groups with the aromatic ring in a temperature range of 700 K. The heat capacity, enthalpy, entropy, and Gibbs energy were calculated for the total composition of coal tar with a final boiling point of 300 degrees C taking into account the additivity of thermodynamic functions in a temperature range of 298-1000 K. It was shown that these data can be used in the process modeling of the hydrogenation conversion of the primary coal tar fraction.
