Title (EN) PROCESS FOR PRODUCING PROPYLENE OXIDE
(FR) PROCÉDÉ DE PRODUCTION D’OXYDE DE PROPYLÈNE
Abstract:
(EN) The present invention relates to a process for producing propylene oxide comprising (I) reacting propene with hydrogen peroxide in the presence of a catalyst to give a mixture (Gl) comprising propylene oxide, unreacted propene, and oxygen; (II) separating propylene oxide from mixture (Gl) to give a mixture (GII) comprising propene and oxygen; (III) reducing the oxygen comprised in mixture (GII) at least partially by reaction with hydrogen in the presence of a catalyst comprising Sn and at least one noble metal.
(FR) La présente invention concerne un procédé de production d’oxyde de propylène consistant à : (I) faire réagir un propène avec du peroxyde d’hydrogène en présence d’un catalyseur afin d’obtenir un mélange (Gl) contenant de l’oxyde de propylène, du propène n’ayant pas réagi et de l’oxygène ; (II) séparer l’oxyde de propylène du mélange (Gl) afin d’obtenir un mélange (GII) contenant du propène et de l’oxygène ; (III) réduire au moins en partie la quantité d’oxygène contenue dans le mélange (GII) en le faisant réagir avec de l’hydrogène en présence d’un catalyseur renfermant du Sn et au moins un métal noble.
