[EN] The characterization and catalytic performance of Zn/ZSM-5 and Zn-B/ZSM-5 catalysts in the n-hexane aromatization was reported. Catalysts were prepared by post-synthesis ion exchange and thoroughly characterized by means of XRD, Py-FTIR, N-2 adsorption, Al-27 and B-11 MAS NMR spectroscopy and electron microscopy techniques. The incorporation of zinc reduces the Bronsted acid site density and increases the Lewis acidic sites of the final ZSM-5 based catalysts. The presence of boron slightly reduces the initial activity of the catalyst but slows down its deactivation rate.
