Conclusions
-
1.
A kinetic model has been established for the hydrogenation of C6-C9 olefins on a palladium sulfide catalyst at atmospheric pressure in the presence of benzene, toluene, and xylenes, according to which the aromatic hydrocarbons inhibit the reaction due to adsorptive displacement.
-
2.
When hydrogen is replaced by deuterium, kinetic isotope effects are observed in hydrogenation as well as in isomerization; this indicates the participation of hydrogen in the slow stages of both reactions.
-
3.
The hydrogenation rates of the individual olefins in mixtures can be calculated on the basis of constants determined in the investigation of the individual olefins, i.e., simple interactions take place in the system.
