A comparative study of hydrosilane compounds as cocatalysts in the metathesis of 1-hexene
(Elsevier B.V., 1998-12-21)
The selectivity of I-hexene metathesis using WCI6 as catalyst was evaluated with a series of hydrosilane-compounds as cocatalysts: Ph3SiH, Ph2SiH2, PhSiH3 and polymethylhydrosiloxane (PMHS). The metathesis reaction is ...
On-line mass spectrometry of the electro-oxidation of methanol in acidic media on tungsten carbide
(SPRINGER, 2008)
The electro-oxidation of methanol at supported tungsten carbide (WC) nanoparticles in sulfuric acid solution was studied using cyclic voltammetry, potentiostatic measurements, and differential electrochemical mass spectroscopy ...
Kinetic study of the partial hydrogenation of 1-heptyne on tungsten oxide supported on alumina
(John Wiley & Sons Ltd, 2012-03)
BACKGROUND: Partial hydrogenation of alkynes have industrial and academic relevance on a large scale; industries such as petrochemical, pharmacology and agrochemical use these compounds as raw material. Typical commercial ...

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 ...

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 ...
Structure and Vibrational Properties of Potassium-Promoted Tungsten Oxide Catalyst Monomeric Sites Supported on Alumina (K2O/WO3/Al2O3) Characterized Using Periodic Density Functional Theory
(American Chemical Society, 2018-10)
Al2O3-supported tungsten oxide catalysts have been instrumental in many industrially relevant reactions and their reactivity is controlled by their molecular structure. In turn, their molecular structure has primarily been ...
