Bimetallic PtSn catalyst for the selective hydrogenation of furfural to furfuryl alcohol in liquid phase
(Elsevier Science, 2009-05-20)
Bimetallic PtSn catalysts, containing different amounts of tin, were obtained by means of controlled surface reactions and used in the liquid-phase hydrogenation of furfural. All the studied systems allowed to obtain fufuryl ...
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 ...
Effect of particle size in the hydrogenation of crotonaldehyde on supported Pt and Pt-Sn catalysts
(Springer, 2002-03)
The present work reports the effect of metal particle size on the selectivity to crotyl alcohol (SUOL) in the liquid phase hydrogenation of crotonaldehyde over SiO2 and α-Al2O3-supported Pt and Pt-Sn catalysts. It was ...
Characterization and catalytic performance of PtSn catalysts supported on Al2O3 and Na-doped Al2O3 in n-butane dehydrogenation
(Springer, 2007-11)
PtSn/Al2O3 and PtSn/Al2O3-Na catalysts display important modifications of the metallic phase with respect to Pt/Al2O3 one. In this sense, TPR and XPS results show the presence of strong interactions between Pt and Sn, with ...
New PtSn structured catalysts with ZnAl2O4 thin film for n-butane dehydrogenation reaction
(Elsevier Science, 2019-11)
Starting from structured supports based on compact spheres coated with a thin and porous layer of ZnAl2O4, mono and bimetallic catalysts were prepared. These catalysts were applied for the n-butane dehydrogenation reaction ...
Catalytic performance in citral hydrogenation and characterization of PtSn catalysts supported on activated carbon felt and powder
(Elsevier Science, 2005-03)
The liquid phase citral hydrogenation carried out at 70 °C and atmospheric pressure over Pt and PtSn catalysts supported on both activated carbon powder (C) and felt (ACf), was investigated. It was found that the addition ...
