Abstract EN
The effect of preparation by ion exchange method and impregnation aqueous Hexachloroplatine acid (40 wt.
% Pt) on structural changes were studied.
Two synthetic zeolites of different compositions were prepared by ion exchange using (NH4CL) and calcinations at 350℃ for 2hr.
Then subsequently loaded with 0.5 wt.
% Pt by impregnations with aqueous hexachloroplatine acid (H2PtCl6.6H2O) and calcinations and reduced with hydrogen.
The compositions analyzed before preparation by X-ray Florence (XRF) and X-ray Diffraction (XRD) and then analyzed after preparation via Scanning Electronic Microscopy (SEM).
The morphology and average crystallite size of γ-Al2O3 was 7μm, while for β Co-Crystalline Zeolite was 8.5μm.
Platinum particles were found to be homogeneously distributed and the crystallite faujasite size range (5-10) μm.
When analyzed via Energy Dispersive X-ray (EDAX) they agree well with (XRD) and zeolite composition, and analyzed via Brunauer Emmett Teller (BET) the results of Surface Area m2/mg giving the highest values equivalent 288.86m2/mg and 427.98m2/mg for Pt/H-γ-Al2O3 and Pt/ H-β Co-Crystalline Zeolite respectively and Pore Volume cm3/gm equivalent 0.3199cm3/gm and 0.6603cm3/gm respectively.
