Butanediols production from erythritol on Rh promoted catalyst
(Planta Piloto de Ingeniería Química, 2020-04)
The C-O hydrogenolysis of Erythritol to Butanodiols was studied in aqueous solution at 473 K and 25 bar of H2 using Rh/ReOx/TiO2 and the monometallic Rh/TiO2 and ReOx/TiO2 catalysts. The solids were characterized by ...
Palladium catalysts in the selective hydrogenation of hexa-1,5-diene and hexa-1,3-diene in the liquid phase. E ect of tin and silver addition
(Physical Chemistry Chemical Physics, 1999)
Palladium, palladiumÈtin and palladiumÈsilver catalysts, supported on two alumina samples with di erent
acidity, have been prepared by di usional impregnation for use in the selective hydrogenation of hexa-1,5-
diene and ...
The use of a cation exchange resin for palladium–tin and palladium–indium catalysts for nitrate removal in water
(Journal of Molecular Catalysis A: Chemical, 2013)
A sulfonated poly(styrene–divinylbenzene) (Sty–DVB) was used for preparing bimetallic palladium–tin or palladium–indium catalysts by successive impregnation and catalytic reduction. The use of this acidic support allows ...
On the Surface Nature of Bimetallic PdZn Particles Supported on a ZnO–CeO2 Nanocomposite for the Methanol Steam Reforming Reaction
(Springer, 2018-08)
CO adsorption—as a molecular probe—was studied by transmission IR spectroscopy on pre-reduced Pd and bimetallic PdZn nanoparticles. Palladium was supported (2 wt% Pd) on pure CeO2, ZnO and a ZnO–CeO2 composite (atomic ratio ...
Aqueous phase reforming of polyols from glucose degradation by reaction over Pt/alumina catalysts modified by Ni or Co
(Elsevier Science Inc, 2017-07)
A comparison of Pt-M/Al2O3 catalysts (M = Ni, Co, none) for the aqueous phase reforming (APR) of different polyols that can be obtained from glucose degradation was made. A standard monometallic Pt/Al2O3 catalyst was ...
Obtención selectiva de butanodioles a partir de materias primas renovables
(2021-11-24)
En esta tesis se estudió la obtención selectiva de butanodioles (BDOs) mediante la pérdida de dos grupos OH de la molécula de eritritol mediante C-O hidrogenólisis empleando catalizadores bimetálicos soportados. Existen ...
