Title (EN) A CATALYST RECOVERY AND RECYCLING PROCESS DURING AROMATIC CARBOXYLIC ACID PRODUCTION
(FR) PROCÉDÉ DE RÉCUPÉRATION ET DE RECYCLAGE DE CATALYSEUR PENDANT LA PRODUCTION D'ACIDES CARBOXYLIQUES AROMATIQUES
Abstract: front page image
(EN)The present disclosure provides a process for recovering and recycling a catalyst from the mother liquor generated during the production of aromatic carboxylic acids. The process comprises treating the mother liquor with an alkyl aromatic compound and further treating the first aqueous layer obtained with an ionic liquid to obtain a catalyst rich aqueous mixture. The catalyst rich aqueous mixture is recycled to the oxidation reactor.
(FR)La présente invention concerne un procédé de récupération et de recyclage d'un catalyseur à partir de la liqueur mère générée pendant la production d'acides carboxyliques aromatiques. Le procédé comprend le traitement de la liqueur mère avec un composé aromatique alkyle et en outre le traitement de la première couche aqueuse obtenue avec un liquide ionique pour obtenir un mélange aqueux riche en catalyseur. Le mélange aqueux riche en catalyseur est recyclé vers le réacteur d'oxydation.
