Title (EN) CATALYST PRECURSOR
(FR) PRÉCURSEUR DE CATALYSEUR
Abstract: front page image
(EN)A method is described for making a dry particulate catalyst precursor comprising one or more amorphous metal hydroxycarbonates of Cu and Zn, including Georgeite and/or zincian Georgeiteby (i) contacting a solution comprising a soluble copper compound and a soluble zinc compound, with a supercritical carbon dioxide antisolvent to precipitate the catalyst precursor, (ii) recovering the precipitate and (iii) drying the precipitate.
(FR)Cette invention concerne un procédé de préparation d'un précurseur de catalyseur particulaire sec comprenant un ou plusieurs hydroxycarbonates métalliques amorphes de Cu et Zn, notamment la géorgéite et/ou la géorgéite zincifère par (i) mise en contact d'une solution comprenant un composé de cuivre soluble et un composé de zinc soluble, avec un antisolvant de dioxyde de carbone supercritique pour précipiter le précurseur de catalyseur, (ii) récupération du précipité et (iii) séchage du précipité.
