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, N₂ adsorption, ²⁷Al and ¹¹B MAS NMR spectroscopy and electron microscopy techniques. The incorporation of zinc reduces the Brønsted 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.

促进硼对的芳构化的物理化学性质和Zn / ZSM-5的催化性能的影响Ñ己烷

报道了Zn / ZSM-5和Zn-B / ZSM-5催化剂在正己烷芳构化反应中的表征和催化性能。通过合成后的离子交换制备催化剂，并通过XRD，Py-FTIR，N ₂吸附，²⁷ Al和¹¹ B MAS NMR光谱学以及电子显微镜技术对其进行全面表征。锌的引入降低了最终ZSM-5基催化剂的布朗斯台德酸位点密度并增加了路易斯酸位点。硼的存在会稍微降低催化剂的初始活性，但会减慢其失活速率。
