Abstract
1. In an investigation of the catalytic properties and photoelectron spectra of Pt-containing high-silica zeolites of the Pentasil type (Pt/H-TsVM) in the aromatization of ethane, it has been established that the catalyst activity and the electronic state of the Pt depend considerably on the conditions of pretreatment and will change under the influence of the reaction medium. 2. In the course of ethane aromatization in the pulse mode, development of activity is observed in the Pt/H-TsVM catalyst, accompanied by an increase in the positive charge on the high-dispersity platinum particles, the presence of which apparently determines the aromatizing activity of Pt/H-TsVM in ethane conversions.
