Abstract
(EN)
The present invention relates to a method for regenerating a carboxylic acid or carboxylate hydrogenation catalyst and, more specifically, to a method for regenerating a hydrogenation catalyst to be used in a reaction of converting a dicarboxylic acid group into a diol group. The present invention provides an effect of regenerating a catalyst deactivated by the deposition of esters to be generated in a reaction of converting a dicarboxylic acid group into a diol group.

La présente invention concerne un procédé de régénération d'un catalyseur d'hydrogénation d'acide carboxylique ou de carboxylate et, plus particulièrement, un procédé de régénération d'un catalyseur d'hydrogénation à utiliser dans une réaction de conversion d'un groupe d'acide dicarboxylique en un groupe diol. La présente invention concerne un effet de régénération d'un catalyseur désactivé par dépôt d'esters à générer dans une réaction de conversion d'un groupe d'acide dicarboxylique en un groupe diol.

본 발명은 카복실산 또는 카르복실산-에스테르 수소화 촉매의 재생 방법에 관한 것으로, 보다 자세하게는 다이카르복실산 작용기(dicarboxylic acid group)를 다이알코올 작용기(diol group)로 전환하는 반응에서 사용되는 수소화 촉매의 재생방법에 관한 것이다. 본 발명에 따르면 다이카르복실산 작용기를 다이알코올 작용기로 전환하는 반응에서 생성되는 ester 물질의 침적에 의한 촉매 비활성화를 회복하는 효과를 제공한다.
