Abstract
Exhaustive hydrogenation of polyaromatic compounds with different extents of condensation (benzene, biphenyl, terphenyl) is studied. The reactions of catalytic dehydrogenation of the polycyclic naphthenic hydrocarbons (cyclohexane, bicyclohexyl, perhydroterphenyl) produced by hydrogenation of the aromatic substrates on a 3%Pt/Sibunit catalyst are explored in a flow setup in the temperature range 260–340°С at the liquid hourly space velocity of 1h−1. The directions of dehydrogenation of each of the studied substrates are studied in detail. Correlation dependences showing the effect of the structure of the molecules under study on their conversion in the dehydrogenation process are revealed. The influence of isomerization of steric and structural isomers on the kinetics of the entire process is established.
