Calculation of the thermodynamic parameters of a fraction of primary coal tar

Resumo

The hydrogenation of a light fraction of primary coal tar was carried out in the presence of ß-FeOOH, Fe₂O₃, and Fe₃O₄ nanocatalysts in a temperature range from 298 to 1000 K. Phenols were removed by extraction with an alcoholic solution. The thermodynamic functions, such as heat capacity, entropy, enthalpy, and Gibbs energy, of the fraction of primary coal tar and a dephenolized fraction of the primary coal tar were calculated.
