In this study, the ultrasonic method was applied to prepare Mo/ZSM-5 catalysts. The evaluation Mo/ZSM-5 for methane dehydroaromatization was carried out in a fixed bed reactor along with an integrated on-line gas chromatography and mass spectrometry system. The fresh and spent catalysts were characterized by using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). The work shows that Mo/ZSM-5 catalysts prepared with the ultrasonic method have higher activity and stability than those prepared without use of ultrasonic method.
