The invention concerns a method for immobilising a catalyst, in particular an oxidation or synthesis catalyst, on supports for contacting said catalysts with solutions or liquids during treatment. The invention is characterised in that the catalyst deposit is performed by: soaking the support in a fluid mixture of the catalyst powder and of a precursor of said catalyst, that is a complex organic compound of the catalytic metal element; extracting with controlled speed the support after immersion in said mixture; drying at room temperature, heat treatment of the resulting support impregnated with the catalyst in conditions ensuring said catalyst adherence on its support.
Procédé d'immobilisation de catalyseur, notamment de catalyseur d'oxydation ou de synthèse, sur des supports permettant de mettre en contact lesdits catalyseurs avec des solutions ou des liquides en cours de traitement, caractérisé en ce que le dépôt du catalyseur s'effectue par: trempage du support dans un mélange fluide de poudre du catalyseur et d'un précurseur dudit catalyseur, c'est-à-dire d'un composé organique complexe de l'élément métallique catalyseur; extraction à vitesse contrôlée du support après immersion dans ledit mélange, séchage à température ambiante, traitement thermique du support ainsi imprégné du catalyseur dans des conditions assurant l'adhérence dudit catalyseur sur son support.
