Insights into size-dependent activity and active sites of Au nanoparticles supported on TS-1 for propene epoxidation with H2 and O2

open access: yes, 2014
Propene epoxidation with H 2 /O 2 is a typical structure-sensitive reaction. For a given support containing tetra-coordinated Ti species such as TS-1, the catalytic activity is greatly influenced by supported Au nanoparticle size.

Gold nanoparticle catalysts for the hydro-epoxidation of propene: an insitu XANES and catalytic study into the adsorption of propene on gold

open access: yes, 2008
Gold nanoparticle catalysts for the direct epoxidation of propene are investigated. The adsorption of propene on the gold nanoparticles is studied using both catalytic experiments and by in-situ XANES analysis. The hydrogen oxidation over gold is used as

Propene epoxidation with H2/H2O/O-2 mixtures over gold atoms supported on defective graphene: A theoretical study

open access: yes, 2012
[EN] The mechanism of propene epoxidation by H-2/H2O/O-2 mixtures catalyzed by gold atoms supported on defective graphene has been investigated by means of periodic density functional theory (DFT) calculations. The fact of being isolated and yet strongly

Direct epoxidation of propene over gold-titanium catalysts : catalyst development and reaction mechanism

open access: yes, 2012
Gold-titania catalysts are attractive to produce propene oxide directly. Very low gold-loaded catalysts have a remarkably high epoxidation activity, not only per amount of gold, but also per total catalyst mass.

Industrial catalytic processes intensification through the use of microreactors [PDF]

open access: yes, 2011
The aim of this work was the intensification of two interesting industrial processes: 1. Biodiesel Production 2. Epoxidized Oils Production In the first case the reaction in traditional industrial reactors is strongly limited by mass transfer, due the ...

Characterization and Catalytic Performance of Deactivated and Regenerated TS‑1 Extrudates in a Pilot Plant of Propene Epoxidation

open access: yes, 2016
TS-1 extrudates that were used for propene epoxidation in a pilot plant for about 1700 h deactivated partly. To study the reason for the deactivation, the deactivated and regenerated catalysts were investigated with X-ray diffraction analysis, Fourier ...

Copolymerization propene non-conjugated dienes: derivatization through hydroboration and epoxidation

open access: yes, 1992
International audienceThe approach described in this paper involved copolymerization of propene with a non conjugated diene so that only one of the two double bonds is incorporated by copolymerization; the second double bond may then be further engaged ...
