Effect of the sequence of impregnation on the activity and sulfur resistance of PtNi/-Al2O3 bimetallic catalysts for the selective hydrogenation of styrene
(Elsevier Science, 2012-06)
The influence of the preparation of bimetallic Pt–Ni catalysts on their activity and sulfur resistance during styrene semi-hydrogenation was studied. The preparation variables assessed were the sequence of impregnation and ...
Spectroscopic and catalytic characterization of Pd-In and Pt-In supported on Al2O3 and SiO2, active catalysts for nitrate hydrogenation
(Elsevier Science, 2008-09)
Bimetallic Pt-In and Pd-In catalysts supported on alumina or silica were studied for the reduction of nitrate to N2 in water, using H2 as reducing agent. Characterization results indicate that bimetallic particles with the ...
Design of catalyst systems for the one-pot synthesis of menthols from citral
(Academic Press Inc Elsevier Science, 2007-04)
Stable, active, and highly selective bifunctional Ni/Al-MCM-41 catalysts were developed for the one-pot synthesis of menthols from citral. The liquid-phase hydrogenation of citral to citronellal was studied on silica-supported ...
CO electrooxidation on PteRu catalysts supported on carbon nanotubes
(Elsevier, 2012-10)
CO electrooxidation studies can be done in relation to either the poisoning effect in methanol fuel cells or to be applied as basis for the development of electrochemical CO sensors. In the present work, Pt and PtRu catalysts ...
Pt–Re–Ge/Al2O3 catalysts for n-octane reforming: Influence of the order of
(Elsevier Science, 2012-03)
Trimetallic Pt–Re–Ge supported catalysts for naphtha reforming were prepared by successive impregnation of suitable precursors on gamma alumina. The order of addition of these precursors was varied and its influence on the ...
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 ...
Effect of Boron Promotion on Coke Formation during Propane Dehydrogenation over Pt/γ-Al 2 O 3 Catalysts
(American Chemical Society, 2020-04)
The effect of boron promotion on the performance of 3 wt.% Pt/γ-Al2O3 catalysts during propane dehydrogenation was investigated. A series of boron-promoted Pt/XB-γ-Al2O3 catalysts were synthesized, tested, and characterized. ...
Renewable H2 from Glycerol Steam Reforming: Effect of La2O3 and CeO2 Addition to Pt/Al2O3 catalysts.
(Wiley VCH Verlag, 2010-05)
Glycerol is the main byproduct of biodiesel production and its increased production volume derives from the increasing demand for biofuels. The conversion of glycerol to hydrogenrich mixtures presents an attractive route ...
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 ...
