“…On the other hand, no diffraction peaks assigned to NiO can be detected, meaning the metal promoters are well dispersed in the base and have a very small crystal size [14,15]. FTIR results of the study illustrated the absorption bands along the wavenumber 500-4000 Cm -1 , in which, the wavenumber of 500-600 Cm -1 corresponded to presence (Zr─O─Zr) bond, the wavenumber of (3300-3750) Cm -1 was corresponded to the presence the vibration of (O-H) bond, while, the absorption bond of SO 4…”

This work deals with preparation of Sulfated Zirconia catalyst (SZ) for isomerization of n-hexane model and refinery light naphtha, as well as enhanced the role of promoters to get the target with the mild condition, stability, and to prevent formation of coke precursors on strong acidic sites of the catalyst. The prepared SZ catalysts were characterization by fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Brunauer –Emmett-Teller (BET) surface area analysis, Thermogravimetric Analysis (TGA), Scanning Electron Microscope (SEM) and atomic force microscopy (AFM) Analyzer. The results illustrate that the maximum conversion and selectivity for n-hexane isomerization with Ni-WSZ and operating temperature of 150 °C was 80.1% and 96 % respectively .Other set of experimental with light naphtha , the results show that the maximum conversion and selectivity with Ni-WSZ and operating temperature of 150 °C was 73.6% and 74% respectively.

In this work, the catalytic properties of palladium catalysts based on Al2O3, SiO2, their mechanical mixtures with SO4-ZrO2 and the Pd/SO4-ZrO2-Al2O3 catalyst in the hexane isomerization reaction were studied. The catalysts were characterized by low-temperature nitrogen adsorption, X-ray diffraction, transmission electron microscopy, temperature-programmed reduction, IR spectroscopy of adsorbed CO, and XPS. It has been shown that the nature of the palladium support and precursor influences the size and charge state of palladium particles in catalysts. It has been established that the most active in the hexane isomerization reaction are catalytic systems in which positively charged forms of palladium are present.
