FT-IR Studies of Acid Properties of Physically Mixed Mo/HZSM-5 Catalysts for Methane Dehydroaromatization

Abstract:

The MoO3/H-ZSM5 catalysts for CH4 dehydroaromatization are prepared by physically mixing MoO3 and HZSM-5 and calcining the mixtures under different atmospheres at different temperatures. Transmission infrared spectra have been used to characterize the acidic properties of the MoO3/HZSM-5 catalysts. On the base of observations obtained the effects of the calicination temperature and environment were discussed on the migration of Mo and its dispersion over HZSM-5.
