Influence of the Brønsted acidity, SiO2/Al2O3 ratio and Rh-Pd content on the ring opening. Part II. Selective ring opening of methylcyclohexane
(Elsevier, 2014-01)
Monometallic and bimetallic Pd-Rh catalysts with various Rh/Pd atomic ratios (=0.5, 1 and 2) and a total metal charge of 1 wt% supported on SiO2-Al2O3(SIRAL 40, 20, 5) were studied for the ring opening of methylcyclohexane ...
Acid or bifunctional mechanism in paraffin isomerization reaction on Pt/SO42−−ZrO2 and Pt/WO3−ZrO2 catalysts
(Elsevier, 2000-09)
At low temperature (300°C) the isomerization of n-C4H10 on Pt/SZ occurs only by a monofunctional acid mechanism. It is necessary to increase the temperature to produce the amount of olefins requiered for the bifunctional ...
Upgrading of diols by gas-phase dehydrogenation and dehydration reactions on bifunctional Cu-based oxides
(Royal Society of Chemistry, 2014-06)
Biomass-derived short chain polyols can be transformed in valuable oxygenates used as building blocks. The gas phase conversion of a model molecule of 1,3-diols (1,3-butanediol) was studied on bifunctional Cu-Mg, Cu-Al and ...
The key role of adsorbate-catalyst interactions into catalytic activity of [CTA+]-Si-MCM-41 from electron density analysis
(Elsevier, 2021-02-23)
In this work, we analyzed the role of the interactions involved in the reaction mechanism for the transesterification of ethyl acetate and methanol on the pore mouth of [CTA+]-Si-MCM-41 catalyst. The Quantum Theory of Atoms ...
EQCM and RDE/RRDE Study of Soluble Iron Phthalocyanine Bifunctional Catalyst for the Lithium-Oxygen Battery
(Electrochemical Society, 2017-12)
Soluble iron phtalocyanine (FePc) has been studied as a bifunctional catalyst for the oxygen reduction reaction (ORR) and oxygenevolution (OER) in lithium air cathodes by means of electrogravimetry with shear wave dissipation, ...
Methanol synthesis from CO2/H2 using Ga2O3-Pd/SiO2 catalysts: Impact of reaction products
(Elsevier Science, 2008-12)
The synthesis of CH3OH from CO2/H2 mixtures using Ga2O3–Pd/SiO2 promoted catalysts is strongly affected by the reaction products. At finite conversion, important amounts of water and carbon monoxide are also found in the ...
One-step methyl isobutyl ketone (MIBK) synthesis from 2-propanol: Catalyst and reaction condition optimization
(Elsevier Science, 2007-02)
A gas-phase process for methyl isobutyl ketone (MIBK) synthesis from 2-propanol in one-pot is studied as an alternative to the conventional technology for producing MIBK from acetone (DMK). Bifunctional copper/acid-base ...
Modelling of n-hexadecane Hydroisomerization and Hydrocracking Reactions on a Mo/Hβ-alumina Bi-functional Catalysts, using the Single Event Concept
(Elsevier Science, 2004-05)
Hydrocracking of a long chain paraffin, hexadecane, was carried out on a Mo/Hb-alumina bi-functional catalyst with a weak dehydrogenating function. It was found through an isomerization selectivity analysis that the behavior ...
