Zusammenfassung:The mordenite zeolite is one of the most important industrially zeolites, used as a solid catalyst for various reactions hydrocracking, hydroisomerization, alkylation, reforming, alkane oxidation, Fischer-Tropsch reaction. The aim of this study was to hydrothermal synthesis mordenite zeolite in its sodium form under hydrothermal conditions, in organic-free synthesis. The form HMOR of the zeolite mordenite was obtained by an ion exchange. For the preparation of the catalysts precursor salts were used: ammonium heptamolybdate, nickel nitrate, cobalt nitrate dispersed from the impregnation by incipient wetness impregnation, such impregnated supports were calcined at 550 °C/4h to obtain the catalyst. The zeolite synthesized in the sodium form NaMOR in its ammonium form NH4MOR in form acid HMOR and their catalysts MoO3/HMOR, NiO/HMOR and Co2O3/HMOR were characterized by X-ray diffraction (XRD) and Fluorescence Spectroscopy of by Energy X-ray dispersive (FRX-ED). From the results it was possible to observe the formation of zeolite phase mordenite in its sodium and acid form and the effective impregnation and formation of the proposed catalysts.
