Pentasil-containing catalysts for aromatization of low-molecular-weight hydrocarbons should have a number of functions [1-3], and the most important one is stability of operation for a long time. Previous studies [4] demonstrated the high efficiency of the pentasil-containing catalyst 3-Zn-HTsVM-F modified simultaneously with zinc (3 wt. % in Zeolite) and fluorine by the mixing method.
