A study has been made of the aromatization of C6-C-8 n-alkanes and cyclohexane in the presence of H-SVK zeolites. It has been established that modification by increasing the Si/Al ratio or introducing Pt, Ni and Zn increases the ratio of Lewis and Bronsted acid centres, which promotes an increase in the selectivity of direct aromatization reactions leading to the formation of arenes with a number of carbon atoms corresponding to die initial hydrocarbons.
