Propane oxidative dehydrogenation on VOx/ZrO2 catalysts
(Elsevier Science Inc, 2004-05)
The catalytic properties of the V2O5/ZrO2 system for the oxidative dehydrogenation of propane were studied. Catalysts with different chemical compositions (i.e., vanadium oxide loadings) were prepared, with activation done ...
Propane oxidative dehydrogenation on V-Sb/ZrO2 catalysts
(Springer, 2008-05)
The catalytic properties of V?Sb/ZrO2 and bulk Sb/V catalysts for the oxidative dehydrogenation of propane were studied. Samples were characterized by nitrogenadsorption, temperature-programmed reduction, temperature-programmed ...
Characterization and catalytic performance of PtSn catalysts supported on Al2O3 and Na-doped Al2O3 in n-butane dehydrogenation
(Springer, 2007-11)
PtSn/Al2O3 and PtSn/Al2O3-Na catalysts display important modifications of the metallic phase with respect to Pt/Al2O3 one. In this sense, TPR and XPS results show the presence of strong interactions between Pt and Sn, with ...
3CaH 2 + 4MgB 2 + CaF 2 reactive hydride composite as a potential hydrogen storage material: Hydrogenation and dehydrogenation pathway
(American Chemical Society, 2012-03-16)
A reactive hydride composite (RHC) with initial composition 3CaH 2 + 4MgB 2 + CaF 2 was studied by in situ synchrotron radiation powder X-ray diffraction (SR-PXD) and X-ray absorption near edge structure (XANES) at the B ...
N-decane dehydrogenation on bimetallic PtSn and PtGe catalysts prepared by dip-coating
(Springer, 2013-10)
The catalytic performance of Pt, PtSn and PtGe supported on γ-Al 2O3 (γ-A) deposited by dipcoating of spheres of α-Al2O3 (α-A) was studied in the n-decane dehydrogenation. The effect of Sn and Ge addition to Pt on the ...
The Influence of the amount and impregnation sequence of potassium on the catalytic performance of Vox/Al2O3 for the non-oxidative dehydrogenation of n-butane
(Sociedade Brasileira de Química, 2012-06)
The non-oxidative dehydrogenation of n-butane was studied over potassium-promoted supported vanadium alumina catalysts (at 823 K under atmosphere pressure) to explore the Influence of the amount and the order of potassium ...
Desidrogenação do etilbenzeno sobre compostos de ferro e alumínio
(2003)
Chromium and potassium-doped iron oxides are widely used as industrial catalysts in the dehydrogenation of ethylbenzene to produce styrene. They have several advantages but deactivate with time, because of the loss of ...
Influence of the starting materials on the catalytic properties of iron oxides
(2002)
The effect of iron nitrate, sulfate and chloride on the catalytic properties of hematite toward ethylbenzene dehydrogenation has been studied. Iron nitrate has been the best precursor to prepare the catalysts.
Synthesis and characterization of polymeric activated carbon-supported vanadium and magnesium catalysts for ethylbenzene dehydrogenation
(2008)
The preparation and characterization of activated carbon obtained from the sulfonated styrenedivinylbenzene
copolymer and the effect of vanadium and magnesium on its catalytic activity and
selectivity to styrene were ...
PtSn/γ-Al2O3 isobutane dehydrogenation catalysts: The effect of alkaline metals addition
