Abstrakt: The research topic is the influence of preliminary ultrasonic treatment of coal tar at ArcelorMittal Temirtau on the individual composition of the products of hydrolytic treatment in the presence of iron-bearing composite catalysts with a carbon carrier (Fe2O3/C and FeSO4/C), within a hydrogen atmosphere. In ultrasound treatment with Fe2O3/C catalyst, the tetralin content increases to 23.60%, the dihydrophenanthrene content to 1.47%, and the indane content to 2.26%. For FeSO4/C catalyst, by contrast, the tetralin content increases to 11.09%, the dihydrophenanthrene content to 1.66%, and the tetrahydrophenanthrene content to 1.27%. Acenaphthylene is almost completely hydrogenated to acenaphthene (2.63%). [ABSTRACT FROM AUTHOR]
