Abstract:
(EN) The present invention addresses the problem of achieving: a method for making it possible to reuse a catalyst for carbonate ester production by restoring activity to the catalyst with a simple procedure and without complicated steps such as firing; and a method for using said regenerated catalyst to produce carbonate ester at high yield. This problem is solved by a method for regenerating a catalyst containing CeO2, which is used in a carbonate ester generation reaction for generating carbonate ester from carbon dioxide and alcohol, wherein the method for regenerating the catalyst includes: (a) a separation step for separating the catalyst out as a crude catalyst from a reaction solution of carbon dioxide and alcohol; and (b) a catalyst treatment step for cleaning the crude catalyst with cleaning alcohol to make a purified catalyst.
(FR) La présente invention a pour but de mettre au point : un procédé permettant de réutiliser un catalyseur pour la production d'ester de carbonate en rétablissant l'activité sur le catalyseur avec une procédure simple et sans étapes complexes telles que la cuisson; et un procédé d'utilisation dudit catalyseur régénéré pour produire un ester de carbonate à rendement élevé. Ce but est atteint par un procédé de régénération d'un catalyseur contenant du CeO2, qui est utilisé dans une réaction de génération d'ester de carbonate pour générer un ester de carbonate à partir de dioxyde de carbone et d'alcool, le procédé de régénération du catalyseur comprenant : (a) une étape de séparation pour séparer le catalyseur en tant que catalyseur brut à partir d'une solution de réaction de dioxyde de carbone et d'alcool; et (b) une étape de traitement de catalyseur pour nettoyer le catalyseur brut avec un alcool de nettoyage afin de produire un catalyseur purifié.
(JA) 炭酸エステル製造のための触媒の活性を、焼成等の複雑な工程によらず簡潔な手法で回復させて触媒を再利用可能とする方法、及びそのように再生した触媒を用いて高収率で炭酸エステルを製造する方法を実現する。 上述の課題は、二酸化炭素とアルコールから炭酸エステルを生成する炭酸エステル生成反応において用いられる、CeOを含む触媒の再生方法であって、(a)二酸化炭素とアルコールとの反応液から前記触媒を粗触媒として分離する分離工程と、(b)前記粗触媒を洗浄用アルコールで洗浄して精製触媒とする触媒処理工程とを含む触媒の再生方法により、解決された。
