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 ...
Liquid-phase transfer hydrogenation of furfural to furfuryl alcohol on Cu–Mg–Al catalysts
(Elsevier, 2014-08)
The liquid-phase transfer hydrogenation of furfural on Cu-based catalysts was studied. Catalysts were prepared by incipient wetness impregnation (Cu/SiO2) and co-precipitation (Cu–Mg–Al). The effect of metal-support ...
Liquid-phase transfer hydrogenation of furfural to furfuryl alcohol on Cu-Mg-Al catalysts
(Elsevier, 2015-01)
The liquid-phase transfer hydrogenation of furfural on Cu-based catalysts was studied. Catalysts were prepared by incipient wetness impregnation (Cu/SiO2) and co-precipitation (Cu-Mg-Al). The effect of metal-support ...
Liquid-Phase Selective Hydrogenation of Hexa-1,5-diene and Hexa-1,3-diene on Palladium Catalysts. Effect of Tin and Silver Addition
(Elsevier, 2000-10)
The liquid-phase hydrogenation of hexa-1,5-diene and hexa-1,3-diene on alumina-supported palladium catalysts is investigated with special attention paid to the effects of tin or silver addition. All catalysts show a global ...
Hydrogenation of citral over ruthenium-tin catalysts
(Elsevier Science BvAmsterdamHolanda, 2003)
Promoting effect of zinc on the vapor-phase hydrogenation of crotonaldehyde over copper-based catalysts
(Elsevier Science, 2005-10)
The promoting effect of zinc for the vapor-phase hydrogenation of crotonaldehyde was studied on impregnated Cu/SiO2 and Cu-ZnO/SiO 2, and on coprecipitated Cu-Al2O3 and Cu x-ZnyO2y-ZnAl2O4 catalysts. The reaction was carried ...
Biogas steam reformer for hydrogen production: Evaluation of the reformer prototype and catalysts
(Elsevier B.V., 2018-01-25)
This work aims to investigate a biogas steam reforming prototype performance for hydrogen production by mass spectrometry and gas chromatography analyses of catalysts and products of the reform. It was found that 7.4% ...
Low metal loading catalysts used for the selective hydrogenation of styrene
(Sociedade Brasileira de Química, 2009-11)
A series of Group VIII metal catalysts was obtained for the semi-hydrogenation of styrene. Catalysts were characterized by Hydrogen Chemisorption, TPR and XPS. Palladium, rhodium and platinum low metal loading prepared ...
