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 ...
Metal dispersion and catalytic activity of trimetallic Pt-Re-Sn/Al 2O3 naphtha reforming catalysts
(Elsevier Science, 2005-10)
The chemisorption of CO over mono-, bi- and trimetallic naphtha reforming catalysts containing Pt, Re and Sn in the metallic function was studied. The temperature-programmed reduction (TPR) results show that there are ...
Highly selective and stable multimetallic catalysts for propane dehydrogenation
(John Wiley & Sons Ltd, 2000-07)
Different mono (Pt), bi (Pt–Sn, Pt–Pb, Pt–Ga) and trimetallic (Pt–Sn–Ga) catalysts based on Pt and supported on different materials (Al2O3, Al2O3–K and ZnAl2O4) were tested under severe process conditions in the propane ...
Trimetallic naphtha reforming catalysts. I. Properties of the metal function and influence of the order of addition of the metal precursors on Pt–Re–Sn/ -Al2O3–Cl
(Elsevier, 2004)
Trimetallic Pt–Re–Sn catalysts supported on chlorided alumina were prepared by successive impregnation, following different orders, of the metal precursors. The content of each metal was 0.3% (w/w). The catalysts were ...
Behavior of PtPb/MgAl2O4 catalysts with different Pb contents and trimetallic PtPbIn catalysts in n-butane dehydrogenation
(Elsevier, 2013-08)
The behavior of PtPb/MgAl2O4 catalysts in butenes production through the n-butane dehydrogenation has shown that at low contents, the Pb acts as promoter, improving the conversion and selectivity, whereas at higher contents ...
The Effect of the Addition of Re and Ge on the Properties of Pt/Al2O3
(2005)
The effect of Re and Ge addition to Pt/Al2O3 was studied. Mono-, bi- and a trimetallic catalysts were prepared and characterized by TPR, XPS, TPO and by the n-pentane, cyclohexane (CH) and n-octane reactions. It was found ...
The Effect of the Addition of Re and Ge on the Properties of Pt/Al2O3
(Springer, 2005-10)
The effect of Re and Ge addition to Pt/Al2O3 was studied. Mono-, bi- and a trimetallic catalysts were prepared and characterized by TPR, XPS, TPO and by the n-pentane, cyclohexane (CH) and n-octane reactions. It was found ...
