N2  - Transcripción del resúmen publicado por el autor: A hydrothermal synthesis method for ß zeolite preparation using kaolin as the sole alumina source was investigated. This approach provided a choice to manufacture zeolite ß with a low cost alumina source. The zeolite ß samples were characterized by XRD, IR, SEM, XRF, DSC, and BET surface area measurements. Tunable crystallinity, higher meso- or macroporosity, higher thermal stability, and more Brnsted type acid sites of zeolite ß can be obtained by properly controlling the synthesis conditions using this system. The catalytic evaluation results indicated that zinc-loaded zeolite ß is a good potential FCC naphtha aromatization catalyst. The kaolin derived, 2 wt% zinc-loaded Zn-ß(2) showed higher aromatic yields and better product distribution compared with that of the reference Zn-ß catalyst; it also provided an aromatics yield of 42.26 wt%, which increased by 22.62 wt% compared with the feedstock
