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. ...
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. ...
Pt, PtSn and PtGe catalysts supported on granular carbon for fine chemistry hydrogenation reactions
(Elsevier Science, 2008-04)
Two series of PtSn and PtGe catalysts with different metallic loadings, supported on activated carbon powder, were prepared by successive impregnation. Both the effects of the second metal addition and the Sn or Ge loading ...
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 ...
n-Decane dehydrogenation on Pt, PtSn and PtGe supported on spinels prepared by different methods of synthesis
(Elsevier, 2013-07)
The catalytic performance of Pt, PtSn and PtGe supported on ZnAl2O4 obtained by mechanochemical synthesis (MS) or coprecipitation (COPR) is studied in the production of 1-decene from the n-decane dehydrogenation. The effect ...
Influence of additives on the Pt metal activity of naphtha reforming catalysts
(Elsevier Science, 2009-02)
Alumina supported bimetallic Pt-Re, Pt-Sn and Pt-Ge naphtha reforming catalysts were studied. The Pt concentration was kept constant at 0.3% (weight basis) while the concentration of the second metal was varied in order ...
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 ...
