摘要：

Pd/SO42-/ZrO2/Al(2)O(3)catalysts are prepared and investigated in reaction of isomerization of N-hexane in the work. For comparison Pd/SO42-/ZrO2/Al2O3 catalysts are investigated. It is established that in the field of low temperatures (140 degrees 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 Pd/SO42-/ZrO2/Al2O3. However, isomerization depth (the maintenance of a 2, 2-dimetilbutan in mix of C-6 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. (C) 2015 The Authors. Published by Elsevier Ltd.
