Abstract

Isomerization of n-heptane over platinum catalysts supported on Y, BEA, MOR and ZSM-5 zeolites with different SiO2/Al2O3 ratio in a mixture with alumina was studied. A platinum precursor was represented by aqueous solutions of H2PtCl6 and [Pt(NH3)4]Cl2. The use of hexachloroplatinic acid was shown to increase selectivity of the reaction. Samples containing Y and BEA zeolites demonstrated the highest selectivity and yields of the target products – di- and trimethyl- substituted heptane isomers.
