(322f) Dehydroaromatization of Methane to Benzene, Toluene and Naphthalene in a Fixed Bed Reactor: The Performance of Nano-Fe Added Mo/ZSM-5 Catalysts

Dehydroaromatization of methane to aromatics provides a promising approach for cost-effective conversion of natural gas, which would have significant environmental benefits. This work was designed to study the promoting effect of nano-Fe on Mo/HZSM-5 catalyst and carbon nanotubes formation mechanism in methane dehydroaromatization(MDA). Mo/HZSM-5 and nano-Fe modified catalysts were synthesized, then evaluated in a fixed-bed reactor along with an integrated on-line gas chromatography and a mass spectrometry system. The fresh or/and spent catalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), N₂ adsorption/desorption, thermo-gravimetric analysis (TGA), and Fourier transform infrared spectroscopy (FTIR).
