Direct dehydrogenation of isobutane to isobutene over carbon catalysts

Dehydrogenation of Isobutane with Carbon Dioxide over SBA-15-Supported Vanadium Oxide Catalysts

A series of vanadia catalysts supported on SBA-15 (V/SBA) with a vanadia (V) content ranging from 1% to 11% were prepared by an incipient wetness method. Their catalytic behavior in the dehydrogenation of isobutane to isobutene with CO2 was examined. The catalysts were characterized by N2 adsorption, X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, and temperatur...

Oxidative dehydrogenation of 1-butene to butadiene over carbon nanotube catalysts

The applications of carbon nanotubes (CNTs) as catalysts have attracted much interests in catalysis community due to their unique porous microstructure and chemical properties. One of the promising results is the use of CNTs in the oxidative dehydrogenation (ODH) of ethylbenzene to styrene [1,2]. However, only few works were reported on the use of CNTs or other carbonaceous materials to catalyz...

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)...

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...
