Title
(EN) DIRECT EPOXIDATION CATALYST AND PROCESS
(FR) CATALYSEUR D'ÉPOXYDATION DIRECTE ET PROCÉDÉ AFFÉRENT
Abstract
(EN)
A catalyst, useful for the direct epoxidation of olefins, is disclosed. The catalyst comprises palladium nanoparticles, support nanoparticles, and a titanium zeolite having a particle size of 2 microns or greater. The palladium nanoparticles are deposited on the support nanoparticles to form supported palladium nanoparticles, and the supported palladium nanoparticles are deposited on the titanium zeolite; or the supported palladium nanoparticles are deposited on a carrier having a particle size of 2 microns or greater. The invention also includes a process for producing an epoxide comprising reacting an olefin, hydrogen and oxygen in the presence of the catalyst. The catalysts are more active in epoxidation reactions, while demonstrating the same or better selectivity.

Le catalyseur ci-décrit est utile pour l'époxydation directe des oléfines et comprend des nanoparticules de palladium, des nanoparticules de support, et une zéolite de titane ayant une taille de particules de 2 microns ou plus. Les nanoparticules de palladium sont déposées sur les nanoparticules de support pour former des nanoparticules de palladium supportées, et lesdites nanoparticules de palladium supportées sont déposées sur la zéolite de titane ; ou les nanoparticules de palladium supportées sont déposées sur un support ayant une taille de particules de 2 microns ou plus. Cette invention concerne également un procédé de production d'un époxyde comprenant la réaction d'une oléfine, d'hydrogène et d'oxygène en présence du catalyseur. Les catalyseurs selon l'invention sont plus actifs dans les réactions d'époxydation, tout en faisant preuve d'une sélectivité identique, voire meilleure.
