Ga and In promoters in bimetallic Pt based catalysts to improve the performance in the selective hydrogenation of citral
(Elsevier Science, 2015-05)
In this paper, bimetallic PtGa and PtIn catalysts supported on multiwall carbon nanotubes and carbon Vulcan were used to study the hydrogenation of citral (alpha,beta-unsaturated aldehyde) in liquid phase to produce nerol ...
Ru‐Pt catalysts supported on Al2O3 and SiO2─Al2O3 for the selective ring opening of naphthenes
(Wiley, 2019-11)
Alumina and silica-alumina supported Ru-Pt catalysts were evaluated for the ring opening of naphthenes. Pt, Ru and Ru-Pt catalysts were prepared by impregnation of inorganic precursors over γ-alumina and silica-alumina ...
Influence of Na content on the catalytic properties of Pt-Ir/Al2O3 catalysts for selective ring opening of decalin
(Elsevier, 2014-04)
The influence of the Na addition on Pt-Ir/Al2O3 on the reaction of selective ring opening of decalin and methyl cyclopentane was studied. The catalysts were evaluated by means of TPR, pyridine TPD, TEM, FTIR-CO and by the ...
Selective oxidation of ethanol on V-MCM-41 catalysts
(Elsevier Science, 2019-10-19)
Catalysts V-MCM-41 with different V contents (0.09-0.90 wt.%), synthesized by the template ion-exchange (TIE) method, have been investigated for acetaldehyde production by selective oxidation of ethanol, studying the effects ...
Characterization and catalytic behavior in the n-butane dehydrogenation of trimetallic InPtSn/MgAl2O4 catalysts
(Elsevier Science, 2007-12)
This paper deals with the characterization and catalytic dehydrogenation behavior of trimetallic InPtSn catalysts with different Sn content (from 0.12 wt% up to 1.08 wt%) supported on MgAl2O4. The support was initially ...
Hept-1-yne partial hydrogenation reaction over supported Pd and W catalysts
(Elsevier Science, 2011-04)
In order to increase the production of olefins the partial hydrogenation of alkynes has achieved industrial importance. In this sense catalysts with selective hydrogenation properties may be of potential interest. In this ...
High-Active Metallic-Activated Carbon Catalysts for Selective Hydrogenation
(Hindawi Limited, 2018-07)
A series of low-loaded metallic-activated carbon catalysts were evaluated during the selective hydrogenation of a medium-chain alkyne under mild conditions. The catalysts and support were characterized by ICP, hydrogen ...
Sulfur Resistance of Pt-W catalyst
(Hindawi Publishing Corporation, 2013-01)
The sulfur resistance of low-loaded monometallic Pt catalysts and bimetallic Pt-W catalysts during the partial selective hydrogenation of styrene, a model compound of PYGAS streams, was studied. The effect of metal ...
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 ...
Hydrogenation of diacetyl over composite-supported egg-shell noble metal catalysts
(Springer, 2017-09)
Two composite supports with a mixed inorganic–organic structure were synthesized: BTAl and UTAl. Hydrophilic–hydrophobic dual properties of the supports were suitable for preparing egg-shell-supported metal catalysts for ...
