[ 1 ] - The influence of alumina used as a support on the catalytic properties of Pt/Sn/Al2O3 systems in the dehydrogenation of isobutane
In this research different types of Al2O3 were used as supports to prepare catalysts for dehydrogenation of isobutane to isobutene. These supports were Al2O3 from Merck, Axen and gamma Al2O3 synthesized from Al(OH)3. Sn/Pt/Al2O3 catalysts were prepared by sequential impregnation, at first Pt and then Sn was deposited. Characterization of catalysts was performed by X-ray powder diffraction (XRD)...
[ 2 ] - سنتز کاتالیزور هیدروژنزدایی ایزوبوتان با پایه نانوحفره زئولیتی Y و مقایسه کارایی آن با کاتالیزور صنعتی
DP803, an industrial catalyst used in petrochemical industry for dehydrogenation of isobutane to isobutene, was characterized in the current study. The results showed that zeolite Y is a high performance catalyst. This catalyst was then synthesized using a platinum source (hexachloro platinic acid) and two different tin sources (tributyl tin chloride and SnCl2.2H2O) all on zeolites Y, and then...
