Abstract

Isomerization of n-hexane was carried out in the presence of hydrogen over Pt- and Pt-Re- supported on the matrix of complex composition (natural klinoptilolite clay, alumina-silica gel) and alumina. Pt- catalysts on the compost containing clinoptilolite clay, alumina-silica-gel, decationed and exchanged zeolite (HCeY) showed the isomers selectivity at a wide range of temperature interval (350-450 ^oC ). It was shown that the high activity and selectivity of studied catalysts correlated with the concentration of strong and medium acid sites on the surface of catalysts.
