Abstract:
The structure changes of Mo/ZSM-5 catalysts with different Mo content (2 and 10 wt. % Mo) and Si/Al atomic
ratio (17, 30 and 45) during the methane dehydroaromatization have been investigated by X-ray powder
diffractometry, N2 adsorption and transmission electron microscopy. The treatment of Mo/ZSM-5 catalysts in
reducing atmosphere (CH4 or H2) at about 700oC promotes development of mesoporous system. The pores are
open to the exterior of the zeolite grain and have an entrance diameter of ~ 4-10 nm. It is proposed that
mesopore formation in Mo/ZSM-5 catalyst is connected with the dealumination of zeolite. The mesopore
formation in the parent H-ZSM-5 zeolite by NaOH treatment does not improve the activity of Мо/ZSM-5
catalyst.
