Abstract

Pt/MOR/Al2O3 catalysts with mordenite zeolite contents of 10 to 50 wt % are prepared. Solutions of H2PtCl6 and [Pt(NH3)4]Cl2 are used as precursors of Pt. It is shown by means of transmission electron microscopy (TEM) that the localization of platinum on a MOR/Al2O3 mixed support depends directly on the nature of the metal’s precursor. The catalysts are tested in the isomerization of n-heptane. It is shown that the best samples of catalysts provide yields of the target products (dimethyl and trimethyl substituted isomers of heptanes) on the level of 21 wt % at a temperature of 280°C, while those of a C5+ stable catalyzate are on the level of 79–82 wt %. The catalysts can be used to improve the environmental friendliness of gasolines by employing them in the isomerization of the 70–105°C fraction of directly distilled gasoline.
