1. The Zn-pentasil system was studied by IR spectroscopy based on adsorption of pyridine. It was shown that zinc ions enter cation-xchange sites which are strong B sites. The Zn-HTsVM system is characterized in the general case by the presence of two types of B sites (strongly and weakly acid) and three types of L sites (lattice, Zn2+ in cation-exchange sites, and Zn2+ in the composition of the excess ZnO phase or cluster). 2. The catalytic activity of HTsVM and Zn-HTsVM was studied in reactions of transformation of ethane. The aromatizing activity increases on addition of Zn2+ and attains the maximum with total exchange of protons in the cation-exchange sites for Zn2+. The Zn2+ ions not entering cation-exchange sites drive side reactions of methane formation and condensation.
