Title (EN) DIRECT EPOXIDATION PROCESS USING IMPROVED CATALYST
(FR) PROCÉDÉ D'ÉPOXYDATION DIRECTE UTILISANT UN CATALYSEUR AMÉLIORÉ
Abstract:
(EN) A supported catalyst and a catalyst mixture, useful for the direct epoxidation of olefins, are disclosed. The supported catalyst comprises a noble metal, lead, and a carrier that has been treated by contacting with nitric acid. The catalyst mixture comprises a titanium or vanadium zeolite and the supported catalyst. The invention also includes a process for producing an epoxide comprising reacting an olefin, hydrogen and oxygen in the presence of the catalyst mixture. The process results in significantly reduced alkane byproduct formed by the hydrogenation of olefin.
(FR) La présente invention concerne un catalyseur sur support et un catalyseur mixte, utiles pour l'époxydation directe d'oléfines. Ledit catalyseur sur support comprend un métal noble, du plomb et un support traité par mise en contact avec de l'acide nitrique. Le catalyseur mixte comprend une zéolithe de titane ou de vanadium et ledit catalyseur sur support. L'invention concerne également un procédé de fabrication d'époxyde qui consiste à faire réagir une oléfine, de l'hydrogène et de l'oxygène en présence du catalyseur mixte. Ledit procédé permet de réduire sensiblement le sous-produit alcane formé par hydrogénation de l'oléfine.
