Title (EN) METHOD FOR STABILIZING A CATION EXCHANGE RESIN PRIOR TO USE AS AN ACID CATALYST AND USE OF SAID STABILIZED CATION EXCHANGE RESIN IN A CHEMICAL PROCESS
(FR) PROCEDE DE STABILISATION D'UNE RESINE D'ECHANGE DE CATIONS AVANT SON UTILISATION EN TANT QUE CATALYSEUR ACIDE ET UTILISATION DE CETTE RESINE D'ECHANGE DE CATIONS STABILISEE DANS UN PROCEDE CHIMIQUE
Abstract: front page image
(EN)A method for preventing the degradation of a catalyst during storage of the catalyst and prior to using the catalyst in a chemical process comprising treating the catalyst with an antioxidant and storing the treated catalyst until further use. The stabilized treated catalyst may be used in a process for producing organic chemicals such as in a process for producing bisphenol A.
(FR)L'invention porte sur un procédé de prévention de la dégradation d'un catalyseur pendant le stockage du catalyseur et avant l'utilisation du catalyseur dans un procédé chimique consistant à traiter le catalyseur avec un antioxydant et à stocker le catalyseur traité jusqu'à une utilisation ultérieure. Ce catalyseur traité stabilisé peut être utilisé dans un procédé de fabrication de produits chimiques organiques, par exemple dans un procédé de fabrication de bisphénol A.
