Investigation of Palladium Catalysts in n-hexane Isomerization Reaction

Pd/SO42-/ZrO2/Al2O3catalysts are prepared and investigated in reaction of isomerization of N-hexane in the work. For comparison Pt/SO42-/ZrO2/Al2O3 catalysts are investigated. It is established that in the field of low temperatures (140 °C) the catalyst on the basis of palladium shows high rates comparable to the Pt-containing catalyst. At more high temperatures yielding of isomers for Pd/SO42-/ZrO2/Al2O3 catalyst are lower, than for Pt/SO42-/ZrO2/Al2O3. However, isomerization depth (the maintenance of a 2, 2-dimetilbutan in mix of C6 isomers) for the palladic catalyst in all studied range of temperatures exceeds for 6-10% a similar indicator for the platinum catalyst. For clarification of the role of condition of palladium the catalysts Pd/Al2O3, Pd/SiO2 were prepared and investigated. It was established that the best indicators are reached on the aluminum oxide systems in which palladium is in the oxidized state.
