The deactivation and regeneration properties of the methanol aromatization catalyst, Ag/ ZSM-5, were investigated by a continuous reaction-catalyst regeneration experiment over four cycles. The activity of the catalyst decreased gradually over the long reaction and was only partly recovered after coke burning. Characterization of the regenerated catalyst by X-ray diffraction (XRD) and transmission electron microscope (TEM) revealed that the ZSM-5 framework remained unchanged and that the sintering of the Ag nanoparticles was not serious. Analyses by Fourier transform Infrared spectroscopy (FTIR) and ammonia-temperature programmed desorption (NH3-TPD) experiment confirmed that the hydrothermal de-alumination of the catalyst by water in large amounts at 475 °C during aromatization resulted in a significant loss of Brønsted acidity. Consequently, an irreversible decrease in the aromatization ability of the catalyst was apparent.
