摘要：

The reversible reactions of hydrogenation-dehydrogenation of polycyclic aromatic hydrocarbons with a different extent of condensation (naphthalene, anthracene, biphenyl, meta- and para-terphenyl isomers) were studied in comparison with benzene on a 3%Pt/C catalyst. Hydrogenation of naphthalene and anthracene was carried out at T = 280 degrees C, P = 90 atm, whereas the reaction of benzene, biphenyl and terphenyl isomers was performed at T = 180 degrees C, P = 70 atm in an autoclave. Dehydrogenation of the corresponding polycyclic naphthenes (cyclohexane, decalin, perhydroanthracene, bicyclohexyl, ortho, meta, and para-isomers of perhydroterphenyl) was carried out in the temperature range of 280 to 340 degrees C in a flow setup at the volume hourly space velocity of 1 h(-1). and atmospheric pressure. Correlation dependences of the reaction rates of hydrogenation-dehydrogenation of the studied substrates on their structure and extent of condensation were found.
