Characterization and catalytic behavior in the n-butane dehydrogenation of trimetallic InPtSn/MgAl2O4 catalysts
(Elsevier Science, 2007-12)
This paper deals with the characterization and catalytic dehydrogenation behavior of trimetallic InPtSn catalysts with different Sn content (from 0.12 wt% up to 1.08 wt%) supported on MgAl2O4. The support was initially ...
Behavior of bimetallic PtSn/Al2O3 catalysts prepared by controlled surface reactions in the selective dehydrogenation of butane
(Elsevier Science, 2009-03)
The "one-pot" circulation reactor system was used for the modification of Pt/Al2O3 catalyst using Controlled Surface Reactions (CSRs) with the involvement of tetraethyltin. At 40 °C the tin anchoring reaction resulted in ...
Butane dehydrogenation on vanadium supported catalysts under oxygen free atmosphere
(Elsevier Science, 2004-09)
The present study investigates the catalytic n-butane dehydrogenation under oxygen free atmosphere using VOx supported on USY, NaY, γ-Al2O3 and α-Al2O3. Experiments are developed at 520°C in a fixed bed microreactor. ...
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 ...
Synthesis of spherical structured catalysts by dip-coating: Application to n-butane dehydrogenation
(John Wiley & Sons Inc, 2017-06)
This work analyzes the deposition conditions of thin layers of γ-Al2O3 by dip-coating on a spherical substrate of α-Al2O3 spheres. Results showed that under controlled deposition conditions, a structured support of α-Al2O3 ...
n-butane dehydrogenation on PtSnIn and PtSnGa trimetallic catalysts supported on structured materials prepared by washcoating
(Elsevier Science, 2021-12)
The aim of this work was to evaluate PtSnIn and PtSnGa catalysts supported on structured materials, composed of a thin layer of γ- Al2O3 deposited on compact spheres of α-Al2O3, in the non-oxidative dehydrogenation of ...
n-Butane Dehydrogenation on PtSn Supported on MAl2O4 (M: Mg or Zn) Catalysts
(Springer, 2004-07)
A study about the performance of PtSn supported on MAl2O4 (M: Mg or Zn) catalysts with low metals loadings (0.3 wt.% Pt, 0.3–0.5 wt.% Sn) in n-butane dehydrogenation is reported in this paper. Catalysts were tested in flow ...
Sol-gel synthesis of V2O5-SiO2 catalyst in the oxidative dehydrogenation of n-butane
(Elsevier Science, 2006-09)
The sol-gel method was used to prepare V-SiO2 catalyst by hydrolysis of vanadium acetylacetonate and silicon alkoxide. Structural changes in the vanadium species upon heat treatment at various temperatures were studied by ...
Oxidative dehydrogenation of propane and n-butane over alumina supported vanadium catalysts
(Planta Piloto de Ingeniería Química, 2004-12)
Structural properties of vanadium dispersed species on γ-A1203 are investigated with the scope to detect changes related with V loading in the oxidative dehydrogenation (ODH) of propane and nbutane. XPS, FTIR, and FTIR of ...
Highly selective and stable bimetallic catalysts supported on different materials for n-butane dehydrogenation
(Elsevier Science, 2009-05)
A study about the performance of Pt(0.3 wt%)Sn(0.3 wt%) catalysts supported on different materials in n-butane dehydrogenation is reported in this paper. The materials used as supports were γ-Al2O3, ZnAl2O4 spinel, MgAl2O4 ...
