Abstract

Cu-ZSM-5, CuZn-ZSM-5 and H-ZSM-5 have been studied for propene aromatization at comparable conditions. It was established that all samples are active for aromatization (yields ⋟50%) and demonstrate high selectivity for benzene, toluene and xylenes formation (⋟ 90%). The role of acid centers in all stage of the aromatization is discussed.

Abstract

Ароматизацию пропена на Cu-ZSM-5, CuZn-ZSM-5 и H-ZSM-5 исследовали в подобных условиях. Образцы цеолитов проявляют почти одинаковую активность к ароматизации (выход ≃ 50%) и обладают высокой селективностью к образованию бензола, толуола и ксилола (≃ 90%). Обсуждают решающую роль кислых центров на всех ступенях ароматизации.
