A study has been made of the influence of the zinc concentration and the introduction of additives of different metals (Pd, Mo, Cr, W) on the activity and stability of a Zn-zeolite-containing catalyst in the aromatization of a mixture of C-2-C-4 hydrocarbon gases. It has been established that an increase in the zinc concentration from 1 to 10% and also the introduction of the above additives increase the operating time of a Zn-TsVM catalyst by a factor of 2-10. The dependence of the composition of the aromatization products on the zinc concentration in the catalyst and the operating time of the latter has been studied.
