Acid-metal modified HZSM-5 catalyst for methanol aromatization

It comprises characterization and catalytic evaluation data obtained from XRD, N₂ adsorption–desorption, NH₃-TPD, Py-FTIR, XPS, FTIR, Raman, and TGA analyses, totaling 12 data files.Specifically, Files 1–4 contain XRD, N₂ adsorption–desorption, NH₃-TPD/Py-FTIR, and XPS data of fresh HZSM-5 zeolites before and after modification, which are used to elucidate the effects of synergistic modification on crystal structure, pore structure, acidity characteristics, and the chemical states of Zn species.

Files 5–6 provide the raw catalytic data, including methanol conversion, oil-phase yield, BTX selectivity, and product distribution, for different HZSM-5 catalysts and L/Zny-ZSM5 (y = 0.1, 0.2, 0.6, and 2.0 wt%) with varying Zn loadings in the methanol-to-aromatics (MTA) reaction. Files 7–11 present XRD, FTIR, Raman, TGA, and N₂ adsorption–desorption data of the spent HZSM-5 zeolites, enabling analysis of structural stability, coke chemical composition, degree of graphitization, and coke-induced pore structure evolution during reaction.
