Role of Sn in Pt-Re-Sn/Al2O3-Cl catalysts for naphtha reforming
(Elsevier Science, 2005-10)
The influence of Sn addition on the catalytic activity of Pt-Re/Al 2O3 naphtha reforming catalysts was studied. Trimetallic Pt-Re-Sn catalysts supported on chlorided alumina were prepared by coimpregnation. The content of ...
High-activity mesoporous Pt/Ru catalysts for methanol oxidation
(American Chemical Society, 2013-10)
High activity mesoporous Pt/Ru catalysts with 2D-hexagonal structure were synthesized using a triblock poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide) copolymer (Pluronic F127) template. The normalized ...
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 ...
Hydrogen purification for fuel cells through CO preferential oxidation using PtCu/Al2O3 structured catalysts
(Elsevier Ltd, 2019-10)
Cordierite monoliths and alumina foams substrates were washcoated with PtCu/Al2O3 powder with a lowloading of Pt (0.2 and 0.5 wt. %) and 4 and 8 wt. % of Cu in order to be used for the CO Preferential Oxidation(COPrOx) ...
Influence of indium content on the properties of Pt-Re/Al2O 3 naphtha reforming catalysts
(Springer, 2010-05)
The influence of indium on the properties of Pt-Re/Al2O 3 catalysts used in naphtha reforming is studied. The addition of indium to the Pt-Re/Al2O3 catalyst produces a big decrease of acidity. It also produces an inhibition ...
Pt-Re-Ge/Al 2O 3 catalysts for n-octane reforming: Influence of the order of addition of the metal precursors
(Elsevier Science, 2012-03)
Trimetallic Pt-Re-Ge supported catalysts for naphtha reforming were prepared by successive impregnation of suitable precursors on gamma alumina. The order of addition of these precursors was varied and its influence on the ...
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 ...
