Hydrogenation of (-)-menthone, (+)-isomenthone, and (+)-pulegone with platinum/tin catalysts
(Springer, 2002-12)
The hydrogenation of (-)-menthone, (+)-isomenthone, and (+)-pulegone over SiO2-supported Pt and Pt-Sn catalysts was studied in this work. The modification with tin was performed by means of the techniques of surface ...
The Wilkinson Complex as a heterogeneous catalyst in the partial hydrogenation of 1-heptyne. regeneration of the complex
(Sociedade Brasileira de Química, 2016-06)
The Wilkinson complex was tested as a catalyst in the partial hydrogenation of 1-heptyne, a medium chain alkyne, at a temperature of T = 303 K and hydrogen pressure PH2 = 150 kPa. The tests were performed in homogeneous ...
Effect of the support on the selective hydrogenation of benzeneover ruthenium catalysts. 1. Al2O3 and SiO2
(Springer, 2005-07)
The effect of the support on the liquid phase selective hydrogenation of benzene to cyclohexene over Ru catalysts was studied. Catalysts were prepared using RuCl3 as precursor and characterized by hydrogen chemisorption, ...
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 ...
Study of the performance of Pt catalysts supported on activated carbon felt and granular carbon for nitrobenzene hydrogenation
(Elsevier Science SA, 2005-11)
The catalytic behavior of the Pt (1 wt%) catalysts supported on purified activated carbon felt (ACF) and powder carbon (C) has been studied in the nitrobenzene (NBZ) hydrogenation reaction in liquid phase after activation ...
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 ...
Influence Of Noble Metals (pd, Pt) On The Performance Of Ru/al2o3 Based Catalysts For Toluene Hydrogenation In Liquid Phase
(Elsevier Science BVAmsterdam, 2016)
Selective liquid-phase hydrogenation of citral over supported bimetallic Pt-Co catalysts
(Elsevier Science, 2009-04)
The liquid-phase hydrogenation of citral was studied at 393 K and 10 bar on Pt-Co/C catalysts, having different Pt/(Pt+Co) ratios and containing a total metal loading of about 2%. The monometallic and bimetallic Pt-Co/C ...
Hydrogen Enrichment in the Catalyzed Gasification of Sawdust
(International Research Journal of Advanced Engineering and Science, 2019-09-20)
The influence of the nickel-based catalyst on the content of hydrogen gas produced by the gasification of sawdust and its effect on organic impurities (tars) at the pilot plant scale is studied. The effect of the reaction ...
Kinetic study of the selective hydrogenation of 3-hexyne over W–Pd/alumina catalysts
(Springer, 2019-04)
Low loaded W-Pd/Alumina are relatively novel catalysts for performing the selective hydrogenation of alkynes, but there is scarce information on the working mechanism. This work studies the kinetics of the selective ...
