Title (EN) PROCESS FOR THE EPOXIDATION OF PROPENE
(FR) PROCÉDÉ D’ÉPOXYDATION DE PROPÈNE
Abstract:
(EN) In a process for the epoxidation of propene with hydrogen peroxide in the presence of an epoxidation catalyst, a shaped epoxidation catalyst is used comprising shaped bodies containing a first titanium silicalite with a titanium content of from 1.0 to 3.0 % by weight, calculated as ΤiΟ2, and a second titanium silicalite with a titanium content of from 3.0 to 5.0 % by weight, the titanium content of the second titanium silicalite being at least 0.1 % by weight higher than the titanium content of the first titanium silicalite.
(FR) La présente invention concerne un procédé d'époxydation de propène avec du peroxyde d'hydrogène en présence d'un catalyseur d'époxydation, un catalyseur d'époxydation formé étant utilisé qui comprend des corps façonnés contenant une première silicalite de titane ayant une teneur en titane de 1,0 à 3,0 % en poids, calculée en tant que ΤiΟ2, et une seconde silicalite de titane ayant une teneur en titane de 3,0 à 5,0 % en poids, la teneur en titane de la seconde silicalite de titane étant d'au moins 0,1 % en poids supérieure à la teneur en titane de la première silicalite de titane.
