Preparación y caracterización de catalizadores trimetálicos de reformado de naftas del tipo Pt-Re-Ge/Al2o3 y Pt-Re-Sn/Al2o3
(2006-09-04)
El objetivo de este trabajo es estudiar la influencia del agregado de Sn y Ge a los catalizadores bimetálicos de Pt-Re/Al2O3 usados en el reformado de nafta y cómo cada metal afecta e influye sobre la actividad catalítica. ...
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 ...
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 ...
Preparación por el método de reducción catalítica de catalizadores Pt-Re-Ge/Al2o3 y Pt-Re-Sn/Al2o3 de reformado de naftas. Caracterización y regeneración
(2008-03-13)
En catalizadores PtReGe/Al2O3 y PtReSn/Al2O3 el tercer metal se depositó empleando distintas técnicas, en reducción catalítica (RC) se varió el medio de impregnación y el porcentaje del tercer metal.
La función metálica ...
Simultaneous deactivation by coke and sulfur of Pt-Re(Ge,Sn)/Al2O3 catalysts for n-hexane reforming
(Elsevier Science, 2000-04)
The simultaneous deactivation by coke and sulfur of monometallic Pt/Al2O3 and bimetallic Pt–Re(Ge, Sn)/Al2O3 catalysts was studied using n-hexane reforming as bifunctional test reaction and thiophene as poisoning molecule. ...
Modification of multimetallic naphtha-reforming catalysts by indium addition
(American Chemical Society, 2009-01)
Pt-Re-Ge/Al2O3 and Pt-Re-Sn/Al2O 3 trimetallic naphtha-reforming catalysts were modified by the addition of indium. This additive negatively modified both the acid and metal functions of the catalysts. It produced a decrease ...
Avalia????o do desempenho de catalisadores do tipo Pt-Re-Sn/Al2O3 na reforma de n-octano.
(Programa de P??s-Gradua????o em Qu??mica da UFBA, 2003)
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 ...
