Stability of Pentasil—Containing Catalysts in Aromatization of the Butane Fraction

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.
